AIRPORT SECURITY/VEHICLE INSPECTION PROCEDURE
The number of vehicular access points into secure areas at IAD has been reduced to an
operational minimum. Those gates that remain open are divided into two categories:
1.
2.
Vehicular gates for approved vehicles and individuals who hold appropriate and valid
airport access media and do not require escorts.
Vehicular gates for those vehicles that have invalid or no airport access authorization
and/or the vehicle operator and passenger(s) do not have valid access authorization media
and require escorts.
B.
The access points for vehicle operator and passenger(s) who have appropriate and valid airport
access media are Gates 127 and 141. Vehicles that require escorts of any type are prohibited at
those gates.
C.
All vehicles and personnel that will require an escort shall enter the AOA via Gates 313, Gate
317, Gate 141, or Gate 118. The vehicle gates at Gate 118 and Gate 141 are designated as AOA
entry points for vehicles and persons that require an escort and their primary work site is located
on the north side of the airport.
Gate 313 is designated as large equipment
contractor/construction access point, and Gate 317 is to be used by contractors and employees
whose primary work site is located on the south side of the airport. These access gates are as
indicated.
D.
Other access gates through which the contractor may gain access to a specific project site are as
indicated and must be approved by Airport Operations and the Transportation Security Agency.
E.
The following procedures will be utilized for all escorted vehicles and AOA approved vehicles
with non-badged passengers seeking entry to the AOA:

Coordinate all vehicle deliveries with the COTR in advance. Provide the vehicle license
plate number and expected delivery time for all vehicle deliveries. Contractor may
compile the expected daily delivery schedule on one sheet for submission to the COTR.
The vehicle operator shall have in his or her possession a commercial manifest, which
identifies the contents of the vehicle and/or trailer.
An escort from the company for whom the shipment is intended shall respond to the
vehicle access gate and remain with the vehicle until the vehicle exits the secured area.
A vehicle search will be conducted and once cleared; vehicles will be permitted escorted
access to their delivery point.
Contractors should expect minor delays up at Gate A as a result of these security
provisions.
Priority consideration may be offered to concrete trucks with resulting delays estimated to
be 20 minutes. To receive priority consideration, schedule concrete deliveries with
Airport Operations and COTR at time of batching.

weather impact, the status and impact of contract modifications, documentation of any
logic changes, and any other changes made to the schedule since the previous monthly
update.
CPM schedule reports listing completed activities, activities in progress, and remaining
activities in the format requested by COTR. For each activity, Contractor shall provide
those details identified in Subparagraph 3.2-D-2.
Monthly and cumulative cash-flow curves that show actual vs. planned cash-flow status.
Documentation of delivered material in the form of paid invoices or other evidence that
Contractor has clear title for the material delivered.
D.
If critical activities of the schedule are delayed and such delay is not excusable as defined in this
Section, the remaining sequence of activities and/or duration thereof shall be adjusted by
Contractor through such measures as additional manpower, additional shifts, or the
implementation of concurrent operations until the schedule produced indicates Work will be
completed on schedule. Except as provided elsewhere in the Contract, all costs incurred by
Contractor to recover from inexcusable delays shall be borne by Contractor.
E.
The monthly schedule update shall form the basis for Contractor's Application for Payment. The
progress payment for an activity shall be based on its agreed on percentage of completion. On
unit-priced contracts, the approval of Contractor's monthly requisition is contingent on the
submittal of a satisfactory monthly schedule update; however, the basis of payment will be the
actual measurement of COTR-accepted, in-place units of work.
3.8
DELAYS AND REQUESTS FOR EXTENSION OF TIME
A.
The determination for an extension of the Contract Time will be made by the Contracting
Officer according to the Contract Provision "Default."
B.
Contractor acknowledges and agrees that delays in activities, irrespective of the party causing
the delay, which according to the computer mathematical analysis do not affect any critical
activity or milestone dates on the CPM network at the time of the delay, shall not become the
basis for an extension of the Contract Time. The only basis for any extension of time will be
the demonstrated impact of an excusable delay on the critical path. In demonstrating such
impact, Contractor shall provide adequate detail as required by the Contract, and Contractor
shall prove that:
1.
2.
3.
4.
5.
6.
C.
An event occurred.
Contractor was not responsible for the event in that the event was beyond the control of
Contractor, and was without fault or negligence of Contractor, subcontractor, or supplier,
and the event was unforeseeable.
The event was the type for which an excuse is granted according to the "Default"
provision of this Contract.
Activities on the critical path of the Work were delayed.
The event in fact caused the delay of the Work.
The requested additional time is an appropriate and reasonable extension of the Contract
Time, given the actual delay encountered.

If unusually severe weather conditions are the basis for a request for an extension of the
Contract Time, such request shall be documented by data substantiating that weather
conditions were abnormal for the period of time and could not have been reasonably
anticipated, and that weather conditions had an adverse effect on the critical activities of
the scheduled construction.
The schedule of anticipated adverse weather below will constitute the base line for
monthly (or a prorated portion thereof) weather/time evaluation by the Contracting
Officer. On issuance of the Notice to Proceed and continuing throughout the Contract on
a monthly basis, actual adverse weather days will be recorded by Contractor on a
calendar day basis (include weekends and holidays) and compared to the monthly
anticipated adverse weather days set forth below.

The number of actual adverse weather days shall be calculated chronologically
from the first to the last day in each month. Contractor shall not be entitled to any
claim for time extension based on adverse weather unless the number of actual
adverse weather days exceeds the number of anticipated adverse weather days, and
unless such adverse weather days prevent work for 50 percent or more of
Contractor's workday. In preparing the Contract Schedule, Contractor shall reflect
the above anticipated adverse weather days on all weather-dependent activities.
Weather-caused delays shall not result in any additional compensation to
Contractor.
On days where adverse weather is encountered, Contractor shall list all critical activities
under progress and shall indicate the impact adverse weather had, if any, on the progress
of such activities. This information shall be presented at the end of the adverse weather
day to COTR or its authorized representative for its review and approval.
If Contractor is found eligible for an extension of the Contract Time, the Contracting
Officer will issue a modification extending the time for Contract completion. The
extension of time will be made on a calendar day basis.

When there are multiple copies of the same sheet with different mark-ups on each copy,
the General Contractor is responsible for consolidating all mark-ups onto a single copy of
each individual sheet.
The information from all RFI's, Change Notices, Design Clarifications, field adjustments,
or any other changes, must be noted on the appropriate drawing. These mark-ups must
include enough information to clearly show the actual constructed conditions resulting
from the change. The information may be drawn onto the drawing, copied onto the
drawing or copied onto a new full size sheet. Every change in construction must have
RFI’s, Change Orders or similar supplementary documents; therefore they must be
copied in original size and attached to the back of the preceding drawing or at the end of
the drawing set, as an appendix, as a full size sheet, same in size as the drawing set.
Multiple RFI’s, CN’s and other supplemental documents may be copied in each single
sheet.
All changes made on the drawings shall reference the appropriate RFI, Change Notices,
Design Clarification, or details from the contractor prepared shop drawings. If the markup is due to a field adjustment, it shall be indicated as such.
Additional Sheets such as shop drawings and sheets showing copies of applicable change
documentation must be inserted into the set as necessary. Such sheets shall have a title
block.
All shop drawings showing information not on the construction drawings (with the
exception of concrete embedded steel reinforcement bending drawings and steel reaction
and fabrication drawings) shall be marked up and included in the record drawing set.
They shall be the same size (changes in scale noted) as all other drawings, include a title
block, and clearly indicate that they are record shop drawings. When the shop drawings
more accurately show locations and conditions, they may be marked in lieu of referenced
on the original drawings. This does not relieve the contractor from the shop drawing

EXCAVATION
No excavation shall be started until the work has been staked out by the Contractor, the Contractor
has obtained elevations and measurements of the ground surface, and the Contractor has submitted
the elevations and measurements of the ground surface to the COTR. All excavated material shall
be disposed of in accordance with Paragraph 2.2H, Disposal of Excavated Materials.
Combustible material shall be removed from the site daily.
The contractor shall be required to process and compact the existing subbase as required in this
section as outlined below. The properties of the existing subbase can be improved by compaction
at proper moisture content.
The Contractor shall immediately notify the Authority Fire Department and the COTR if a release
of a hazardous material occurs or if a hazardous material is detected in the presence of any soil.
Pumping shall be used to maintain the subbase in a dry condition.
A.
PCC Pavement Removal. Pavement removal shall be performed as illustrated on the
drawings and as specified in the paragraph below.
1) The existing concrete to be removed shall be freed from the pavement to remain.
This shall be accomplished by a sequence of wet diamond and wheel saw cuts as
described in the drawings. Overcuts into pavement to remain resulting from planned
sawcuts along the removal limits shall be filled with a COTR approved epoxy
material in accordance with the manufacturer’s instructions. The pavement inside the
initial saw cut shall be broken by methods suitable to the Contractor except as noted
below. If additional sawcuts are used to break the pavement into pieces, overcuts
into pavement to remain shall not be allowed. The Contractor’s removal operation
shall not cause damage to cables, utility ducts, pipelines, or drainage structures under
the pavement.
2) To avoid damaging existing underground utilities, the use of drop hammers or
wrecker balls to break Portland cement pavement slabs will not be permitted; the use
of guillotine breakers will not be permitted over top of existing underground utilities.
When using the guillotine breaker, the Contractor shall suspend pavement breaking
operations a sufficient distance either side of the utility to prevent damage to the
utility. The Contractor shall determine this distance based on type of utility, utility
depth and breaking equipment. The Contractor shall locate all utilities prior to PCC
breaking operations. PCC Pavement removal over top utilities shall be by saw cuts
and hoe rammed method.
3) Edge Repair. The edge of existing concrete pavement against which new pavement
abuts shall be protected from damage at all times. Areas which are damaged during
construction shall be repaired at no cost to the Authority; repair of previously existing
damaged areas will be considered a subsidiary part of concrete pavement
construction.

b. Underbreak Repair. If bottom 1/3 (or less) of the slab needs repairs, the repair
shall be considered an underbreak repair and shall be performed in accordance
with this paragraph. All underbreak shall be repaired. First, all delaminated and
loose material shall be removed. Next, the underlying material shall be
recompacted, without addition of any new material. Finally, the void shall be
completely filled with paving concrete, thoroughly consolidated. Care shall be
taken to produce an even joint face from top to bottom. Prior to placing
concrete, the underlying material shall be thoroughly moistened. After
placement, the exposed surface shall be completely coated with curing
compound.
c. Underlying Material. The underlying material adjacent to the edge of and under
the existing pavement to remain in place shall be protected from damage or
disturbance during removal operations and until placement of new concrete, and
shall be shaped as shown on the drawings, or as directed. Sufficient underlying
material shall be kept in place outside the joint line to completely prevent
disturbance of material under the pavement. Any material under the portion of
the concrete pavement to remain in place that is disturbed or loses its compaction
shall be carefully removed and replaced with concrete as specified in paragraph
“Underbreak Repair”. The underlying material outside the joint line shall be
thoroughly compacted and shall be moist when new concrete is placed.
B.
Overbreak. Overbreak, including slides, is that portion of any material displaced or
loosened beyond the finished work as planned or authorized by the COTR. The COTR
shall determine if the displacement of such material was unavoidable and his/her decision
shall be final. All overbreak shall be graded or removed by the Contractor and disposed
of as directed; however, payment will not be made for the removal and disposal of
overbreak which the COTR determines as avoidable. Unavoidable overbreak will be
classified as "Unclassified Excavation".
C.
Removal of Utilities. The Contractor will accomplish the removal of existing structures
and utilities required to permit the orderly progress of work.
D.
Initial Compaction. After the pavement removal operations have been completed, the
subbase shall be compacted as discussed in Section 152-2.2F "Compaction
Requirements”. Compacting operations shall continue until the maximum attainable
density of the existing subbase has been reached. If the maximum density is less than the
specified percent of maximum density, the Contractor shall either dry the subbase or
sprinkle the subbase with water, as necessary to reach the required moisture content. The
Contractor shall then continue recompacting the subbase until the maximum density
attainable has been reached. If this is less than the specified percent of maximum density,
this process shall be repeated until the Contractor has made at least three attempts to
compact the subbase to the specified percent of maximum density.
E.
Sump Installation and Pumping. During construction trapped moisture in low areas of
the subbase, may cause undesirable conditions. Undrained areas or depressions created in
the subbase by excavation are not permitted at any time in this project. The Contractor

CONSTRUCTION METHODS
209-3.1
OPERATION AT SOURCES OF SUPPLY
The base material shall be obtained from sources approved by the Virginia Department of
Transportation. The material shall be handled in a manner that shall secure a uniform and
satisfactory product.
209-3.2
PREPARING UNDERLYING COURSE FOR NEW PAVEMENTS
The underlying course shall be checked and accepted by the COTR before placing and spreading
operations are started. Any ruts or soft yielding places caused by improper drainage conditions,
hauling, or any other cause shall be corrected at the Contractor's expense before the base course is
placed thereon. Material shall not be placed on frozen subgrade.
209-3.3
MIXING
The aggregate shall be uniformly blended during crushing operations or mixed in a plant. The
plant shall blend and mix the materials to meet the specifications and to secure the proper
moisture content for compaction.
209-3.4
PLACING
The crushed aggregate base material shall be placed on the moistened subbase as needed to level
the existing subbase course.
The maximum depth of a compacted layer shall be 6 inches. If the total depth of the compacted
material is more than 6 inches, it shall be constructed in two or more layers. In multi-layer
construction, the base course shall be placed in approximately equal-depth layers.
The previously constructed layer should be cleaned of loose and foreign material prior to placing
the next layer. The surface of the compacted material shall be kept moist until covered with the
next layer.

COMPACTION
Immediately upon completion of the spreading operations, the crushed aggregate shall be
thoroughly compacted. The number, type, and weight of rollers shall be sufficient to compact the
material to the required density.
The moisture content of the material at the time of compaction operations shall be within 20% of
the optimum moisture content as determined by ASTM D1557, Method C.
The course shall not be rolled when the underlying course is soft or yielding or when the rolling
causes undulation in the base course. When the rolling develops irregularities that exceed 3/8
inch when tested with a l6-foot straightedge, the irregular surface shall be loosened, refilled with
the kind of material as that used in constructing the course, and rolled again as required.
In areas inaccessible to rollers, the base course material shall be tamped thoroughly with
mechanical tampers.
The sprinkling during rolling, if necessary, shall be in the amount and by equipment approved by
the COTR. Water shall be added in such a manner that free water will not reach the underlying
layer and cause it to become soft.
209-3.6
ACCEPTANCE SAMPLING AND TESTING FOR DENSITY
Crushed Aggregate Base Course will only be directly tested for acceptance in locations where the
material is placed at a thickness of more than 4 inches. In areas where the crushed aggregate base
course is less than 4 inches thick, it shall be compacted and tested according to Item P-152.
Crushed Aggregate Base Course will be accepted for density when the field density is at least 95
percent of the maximum density of laboratory prepared specimens. The laboratory density shall
be determined in accordance with ASTM D1557, Method C. The in-place field density shall be
determined in accordance with ASTM D1556 or D2167. If the specified density is not attained,
the layer shall be reworked and/or re-compacted and two additional random tests made. This
procedure shall be followed until the specified density is reached.
In lieu of the core method of field density determination, acceptance testing may be accomplished
using a nuclear gauge in accordance with ASTM D6938. The gauge should be field calibrated in
accordance with paragraph 4 of D6938. Calibration tests shall be conducted on the first lot of
material placed that meets the density requirements.
Use of D6938 results in a wet unit weight, and when using this method, ASTM D3017 shall be
used to determine the moisture content of the material. The calibration curves furnished with the
moisture gauges shall be checked as described in paragraph 7 of D3017. The calibration checks
of both the density and moisture gauges shall be made at the beginning of a job and at intervals as
determined by the COTR.
All acceptance testing and associated costs shall be the Contractor's responsibility.

sources and of different grading shall not be stockpiled together. Improperly placed
stockpiles will not be accepted by the COTR.
501-4.06
B.
Aggregates that have become segregated or mixed with earth or foreign material shall
not be used. All aggregates produced or handled by hydraulic methods, and washed
aggregates, shall be stockpiled or binned for draining at least 12 hours before being
batched. Rail shipments requiring more than 12 hours will be accepted as adequate
binning only if the car bodies permit free drainage. The fine aggregate and coarse
aggregate shall be separately weighed into hoppers in the respective amounts set by
the COTR in the job mix. Cement shall be measured by weight. Separate scales and
hopper, with a device to positively indicate the complete discharge of the batch of
cement into the batch box or container, shall be used for weighing the cement.
C.
Batching plants shall be equipped to proportion aggregates and bulk cement, by
weight, automatically using interlocked proportioning devices of an approved type.
When bulk cement is used, the Contractor shall use a suitable method of handling the
cement from weighing hopper to transporting container or into the batch itself for
transportation to the mixer, such as a chute, boot, or other approved device, to
prevent loss of cement. The device shall be arranged to provide positive assurance
that the cement content specified is present in each batch.
D.
When cement is placed in contact with the aggregates, batches may be rejected unless
mixed within 1-1/2 hours of such contact. Batching shall be conducted so that the
results in the weights of each material required will be within a tolerance of 1 percent
for cement and 2 percent for aggregates.
E.
Water may be measured either by volume or by weight. The accuracy of measuring
the water shall be within plus or minus 1 percent of required amounts. Unless the
water is to be weighed, the water-measuring equipment shall include an auxiliary
tank from which the measuring tank shall be filled. The measuring tank shall be
equipped with an outside tap and valve to provide for checking the setting, unless
other means are provided for readily and accurately determining the amount of water
in the tank. The volume of the auxiliary tank shall be at least equal to that of the
measuring tank.
F.
Methods and equipment for adding air-entraining agent or other admixtures to the
batch, when required, shall be approved by the COTR. All admixtures shall be
measured into the mixer with an accuracy of plus or minus 3 percent.
MIXING CONCRETE
A.
The concrete may be mixed at the work site, in a central mix plant or in truck mixers.
The mixer shall be of an approved type and capacity. Mixing time shall be measured
from the time all materials, except water, are emptied into the drum. All concrete
shall be mixed and delivered to the site in accordance with the requirements of
ASTM C 94, except that the minimum required revolutions of the mixing speed for
transit mixed concrete may be reduced to not less than that recommended by the
mixer manufacturer. The number of revolutions recommended by the mixer
manufacturer shall be indicated on the manufacturer's serial plate attached to the

mixer. The Contractor shall furnish test data acceptable to the COTR verifying that
the make and model of the mixer will produce uniform concrete conforming to the
provisions of ASTM C 94 at the reduced number of revolutions shown on the serial
plate.
B.
When mixed at the work site or in a central mixing plant, the mixing time shall not be
less than 50 seconds nor more than 90 seconds. Mixing time ends when the
discharge chute opens. Transfer time in multiple drum mixers is included in mixing
time. The contents of an individual mixer drum shall be removed before a
succeeding batch is emptied therein.
C.
The mixer shall be operated at the drum speed as shown on the manufacturer's
nameplate on the approved mixer. Any concrete mixed less than the specified time
shall be discarded at the Contractor's expense. The volume of concrete mixed per
batch shall not exceed the mixer's nominal capacity in cubic feet (cubic meters), as
shown on the manufacturer's standard rating plate on the mixer. An overload up to
10 percent above the mixer's nominal capacity may be permitted provided concrete
test data for segregation and uniform consistency are satisfactory, and provided no
spillage of concrete takes place. The batch shall be charged into the drum so that a
portion of the mixing water shall enter in advance of the cement and aggregates. The
flow of water shall be uniform, and all water shall be in the drum by the end of the
first 15 seconds of the mixing period. The throat of the drum shall be kept free of
such accumulations as may restrict the free flow of materials into the drum.
D.
Mixed concrete from the central mixing plant shall be transported in truck mixers,
truck agitators, or non-agitating trucks. The elapsed time from the addition of
cementitous material to the mix until the concrete is deposited in place at the work
site shall not exceed 30 minutes when the concrete is hauled in non-agitating trucks,
nor 90 minutes when the concrete is hauled in truck mixers or truck agitators. Retempering concrete by adding water or by other means will not be permitted, except
when concrete is delivered in transit mixers. With transit mixers additional water
may be added to the batch materials and additional mixing performed to increase the
slump to meet the specified requirements provided the addition of water is performed
within 45 minutes after the initial mixing operations and provided the
water/cementitous ratio specified in the mix design is not exceeded.

concrete finishing equipment may be permitted to ride upon the edges of previously
constructed pavement when the concrete has attained a minimum flexural strength of
400 psi.
E.
Side-Form Method. For the side-form method, the concrete shall be deposited on the
moistened grade to require as little re-handling as possible. Unless truck mixers, truck
agitators, or non -agitating hauling equipment are equipped with means for discharge
of concrete without segregation of the materials, the concrete shall be placed and
spread using an approved mechanical spreading device that prevents segregation of
the materials. Placing shall be continuous between transverse joints without the use
of intermediate bulkheads. Necessary hand spreading shall be done with shovels--not
rakes. Workmen shall not be allowed to walk in the freshly mixed concrete with
boots or shoes coated with earth or foreign substances.

It is the intent of the specification to produce a high quality, dense, long lasting, and
smooth pavement suitable for the high speed operations of roughness-sensitive heavy
jet aircraft. This requires that all joints, and particularly all longitudinal joints, meet
the specified tolerance throughout their length. The COTR will designate the paving
lanes to be used for the initial paving operations. In the event that slumping or
sloughing occurs behind the paver or if there are any other structural or surface
defects which, in the opinion of the COTR, cannot be corrected within permissible
tolerances, paving operations shall be immediately stopped until proper adjustment of
the equipment or procedures have been made. In the event that satisfactory
procedures and pavement are not achieved after not more than 2,000 lineal feet of
single lane paving, the Contractor shall complete the balance of the work with the use
of standard metal forms and the formed method of placing and curing. Any concrete
not corrected to permissible tolerances shall be removed and replaced at the
Contractor's expense.
STRIKE-OFF OF CONCRETE AND PLACEMENT OF REINFORCEMENT
A.
Following the placing of the concrete, it shall be struck off to conform to the cross
section shown on the plans and to an elevation such that when the concrete is
properly consolidated and finished, the surface of the pavement shall be at the
elevation shown on the plans. When reinforced concrete pavement is placed in two
layers, the bottom layer shall be struck off to such length and depth that the sheet of
reinforcing steel fabric or bar mat may be laid full length on the concrete in its final
position without further manipulation. The reinforcement shall then be placed
directly upon the concrete, after which the top layer of the concrete shall be placed,
struck off, and screeded. If any portion of the bottom layer of concrete has been
placed more than 30 minutes without being covered with the top layer or if initial set
has taken place, it shall be removed and replaced with freshly mixed concrete at the
Contractor's expense. When reinforced concrete is placed in one layer, the
reinforcement may be positioned in advance of concrete placement or it may be
placed in plastic concrete by mechanical or vibratory means after spreading.
B.
Reinforcing steel, at the time concrete is placed, shall be free of mud, oil, or other
organic matter that may adversely affect or reduce bond. Reinforcing steel with rust,
mill scale or a combination of both will be considered satisfactory, provided the
minimum dimensions, weight, and tensile properties of a hand wire-brushed test
specimen are not less than the applicable ASTM specification requirements.
JOINTS
A.
Joints shall be constructed as shown on the plans and in accordance with these
requirements. All joints shall be constructed with their faces perpendicular to the
surface of the pavement and finished or edged as shown on the plans. Joints shall not
vary more than 1/2 inch from their designated position and shall be true to line with
not more than 1/4-inch variation in 10 feet. The surface across the joints shall be
tested with a 10-foot straightedge as the joints are finished and any irregularities in
excess of 1/16 inch shall be corrected before the concrete has hardened. All joints

shall be so prepared, finished, or cut to provide a groove of uniform width and depth
as shown on the plans.
B.
Construction. Longitudinal construction joints shall be slip-formed or formed against
side forms, as shown in the plans.
C.
Transverse construction joints shall be installed at the end of each day's placing
operations and at any other points within a paving lane when concrete placement is
interrupted for more than 30 minutes or it appears that the concrete will obtain its
initial set before fresh concrete arrives. The installation of the joint shall be located
at a planned contraction or expansion joint. If placing of the concrete is stopped, the
Contractor shall remove the excess concrete back to the previous planned joint.
D.
Contraction. Contraction joints shall be installed at the locations and spacing as
shown on the plans. Contraction joints shall be installed to the dimensions required
by forming a groove or cleft in the top of the slab while the concrete is still plastic or
by sawing a groove into the concrete surface after the concrete has hardened. When
the groove is formed in plastic concrete the sides of the grooves shall be finished
even and smooth with an edging tool. If an insert material is used, the installation
and edge finish shall be according to the manufacturer's instructions. The groove
shall be finished or cut clean so that spalling will be avoided at intersections with
other joints. Grooving or sawing shall produce a slot at least 1/8 inch wide and to the
depth shown on the plans.
E.
Expansion. Expansion joints shall be installed as shown on the plans. The premolded filler of the thickness as shown on the plans, shall extend for the full depth
and width of the slab at the joint, except for space for sealant at the top of the slab.
The filler shall be securely staked or fastened into position perpendicular to the
proposed finished surface. A cap shall be provided to protect the top edge of the
filler and to permit the concrete to be placed and finished. After the concrete has
been placed and struck off, the cap shall be carefully withdrawn leaving the space
over the pre-molded filler. The edges of the joint shall be finished and tooled while
the concrete is still plastic. Any concrete bridging the joint space shall be removed
for the full width and depth of the joint.
F.
Tie bars. Tie bars shall consist of deformed bars installed in joints as shown on the
plans. Tie bars shall be placed at right angles to the centerline of the concrete slab
and shall be spaced at intervals shown on the plans. They shall be held in position
parallel to the pavement surface and in the middle of the slab depth. These bars shall
not be painted, greased, or enclosed in sleeves.
G.
Dowel bars. Dowel bars or other load-transfer units of an approved type shall be
placed across joints in the manner as shown on the plans. They shall be of the
dimensions and spacings as shown and held rigidly in the middle of the slab depth in
the proper horizontal and vertical alignment by an approved assembly device to be
left permanently in place. The dowel or load-transfer and joint devices shall be rigid
enough to permit complete assembly as a unit ready to be lifted and placed into
position. The portion of each dowel painted with rust preventative paint, as required
under paragraph 2.07, shall be thoroughly coated with asphalt MC-70, or an

approved lubricant, to prevent the concrete from bonding to that portion of the dowel.
If free-sliding plastic-coated or epoxy-coated steel dowels are used, a lubrication
bond breaker shall be used except when approved pullout tests indicate it is not
necessary. Where butt-type joints with dowels are designated, the exposed end of the
dowel shall be oiled.
H.
Dowel bars at contraction joints may be placed in the full thickness of pavement by a
mechanical device approved by the COTR. The device shall be capable of installing
dowel bars within the maximum permissible alignment tolerances. Dowels bars at
longitudinal construction joints shall be bonded in drilled holes.
I.
Drilling and Grouting. Load transfer shall be restored to joints at the edges of panel
replacement. The load transfer device shall be dowel bars or tie bars, as shown in the
plans. The load transfer devices shall be placed only by means of bonding the
dowels into holes drilled with a pneumatic, percussive or core drill into the hardened
concrete. Holes approximately 1/8 inch greater in diameter than the dowels shall be
drilled into the hardened concrete and the dowels shall be bonded in the drilled holes
using an epoxy-resin material as specified in paragraph 2.11, Class as appropriate for
the existing temperature conditions. The error in final alignment of any dowel from
its indicated alignment after the pavement has been finished shall not be greater than
1/8 inch per foot.
J.
Installation. All devices used for the installation of expansion joints shall be
approved by the COTR.
K.
The top of an assembled joint device shall be set at the proper distance below the
pavement surface and the elevation shall be checked. Such devices shall be set to the
required position and line and shall be securely held in place by stakes or other means
to the maximum permissible tolerances during the pouring and finishing of the
concrete. The pre-molded joint material shall be placed and held in a vertical
position; if constructed in sections, there shall be no offsets between adjacent units.
L.
Dowel bars and assemblies shall be checked for position and alignment. The
maximum permissible tolerances on dowel bar alignment shall be in accordance with
paragraph 5.02.I.9. During the concrete placement operation, it is advisable to place
plastic concrete directly on dowel assemblies immediately prior to passage of the
paver to help maintain dowel position and alignment within maximum permissible
tolerances.
M.
Dowels and tie bars shall be placed in longitudinal construction joints by bonding the
dowels or tie bars into holes drilled into the hardened concrete. Holes approximately
1/8-inch to 1/4-inch greater in diameter than the dowel or tie bar shall be drilled with
rotary-type core drills that must be held securely in place to drill perpendicularly into
the vertical face of the pavement slab. Rotary- type percussion drills may be used
provided that spalling of concrete does not occur and the concrete has cured for 48
hours. Any damage of the concrete shall be repaired by the Contractor in a method
approved by the COTR. Dowels or tie bars shall be bonded in the drilled holes using
an epoxy resin material. Installation procedures shall be adequate to insure that the
area around dowels is completely filled with epoxy grout. Epoxy shall be injected

into the back of the hole and displaced by the insertion of the dowel bar. Bars shall
be completely inserted into the hole and shall not be withdrawn and reinserted
creating air pockets in the epoxy around the bar. The Contractor shall furnish a
template for checking the position and alignment of the dowels. Dowel bars shall not
be less than 7-1/2 inches from a transverse joint and shall not interfere with dowels in
the transverse direction.
N.
501-4.11
Sawing of Joints. Joints shall be cut as shown on the plans. Equipment shall be as
described in paragraph 4.01.F. The circular cutter shall be capable of cutting a
groove in a straight line and shall produce a slot at least 1/8 inch wide and to the
depth shown on the plans. The top portion of the slot shall be widened by sawing to
provide adequate space for joint sealers as shown on the plans. Sawing shall
commence as soon as the concrete has hardened sufficiently to permit cutting without
chipping, spalling, or tearing and before uncontrolled shrinkage cracking of the
pavement occurs. Sawing shall be carried on both during the day and night as
required. The joints shall be sawed at the required spacing, consecutively in
sequence of the concrete placement. Immediately after sawing the joint, the resulting
slurry shall be completely removed from the pavement surface (without damaging the
surface), using vacuum sweepers, brooms or other methods before the slurry is
allowed to dry. After the initial sawcut, the contractor shall reapply the curing
compound to the sawed joint.
FINAL STRIKE-OFF, CONSOLIDATION, AND FINISHING
A.
Sequence. The sequence of operations shall be the strike-off, floating and removal of
laitance, straight edging, and final surface finish. The addition of superficial water to
the surface of the concrete to assist in finishing operations will not be permitted. If
the application of water to the surface is permitted, it shall be applied as a fog spray
by means of approved spray equipment.
B.
Finishing at Joints. The concrete adjacent to joints shall be compacted or firmly
placed without voids or segregation against the joint material; it shall be firmly
placed without voids or segregation under and around all load-transfer devices, joint
assembly units, and other features designed to extend into the pavement. Concrete
adjacent to joints shall be mechanically vibrated as required in paragraph 4.08.E.2.
After the concrete has been placed and vibrated adjacent to the joints, the finishing
machine shall be operated in a manner to avoid damage or misalignment of joints. If
uninterrupted operations of the finishing machine, to, over, and beyond the joints,
cause segregation of concrete, damage to, or misalignment of the joints, the finishing
machine shall be stopped when the screed is approximately 8 inches from the joint.
Segregated concrete shall be removed from the front of and off the joint; and the
forward motion of the finishing machine shall be resumed. Thereafter, the finishing
machine may be run over the joint without lifting the screed, provided there is no
segregated concrete immediately between the joint and the screed or on top of the
joint.
C.
Machine Finishing. The concrete shall be spread as soon as it is placed, and it shall
be struck off and screeded by a finishing machine. The machine shall go over each
area as many times and at such intervals as necessary to give to proper consolidation

and to leave a surface of uniform texture. Excessive operation over a given area shall
be avoided. When side forms are used, the tops of the forms shall be kept clean by an
effective device attached to the machine, and the travel of the machine on the forms
shall be maintained true without lift, wobbling, or other variation tending to affect the
precision finish. During the first pass of the finishing machine, a uniform ridge of
concrete shall be maintained ahead of the front screed for its entire length. When in
operation, the screed shall be moved forward with a combined longitudinal and
transverse shearing motion, always moving in the direction in which the work is
progressing, and so manipulated that neither end is raised from the side forms during
the striking-off process. If necessary, this shall be repeated until the surface is of
uniform texture, true to grade and cross section, and free from porous areas.
D.
Hand Finishing. Hand finishing methods will not be permitted, except under the
following conditions: in the event of breakdown of the mechanical equipment, hand
methods may be used to finish the concrete already deposited on the grade; in areas
of narrow widths or of irregular dimensions where operation of the mechanical
equipment is impractical. Concrete, as soon as placed, shall be struck off and
screeded. An approved portable screed shall be used. A second screed shall be
provided for striking off the bottom layer of concrete when reinforcement is used.
1.
The screed for the surface shall be a least 2 feet longer than the maximum width of
the slab to be struck off. It shall be of approved design, sufficiently rigid to retain its
shape, and shall be constructed either of metal or of other suitable material covered
with metal. Consolidation shall be attained by the use of suitable vibrators.
E.
Floating. After the concrete has been struck off and consolidated, it shall be further
smoothed and trued by means of a longitudinal float using one of the following
methods:
1.
Hand Method. Long-handled floats shall not be less than 12 feet in length
and 6 inches in width, stiffened to prevent flexibility and warping. The float
shall be operated from foot bridges spanning but not touching the concrete or
from the edge of the pavement. Floating shall pass gradually from one side
of the pavement to the other. Forward movement along the centerline of the
pavement shall be in successive advances of not more than one-half the
length of the float. Any excess water or laitance in excess of 1/8-inch thick
shall be removed and wasted.
2.
Mechanical method. The Contractor may use a machine composed of a
cutting and smoothing float(s), suspended from and guided by a rigid frame
and constantly in contact with, the side forms or underlying surface. If
necessary, long-handled floats having blades not less than 5 feet in length
and 6 inches in width may be used to smooth and fill in open-textured areas
in the pavement. When the crown of the pavement will not permit the use of
the mechanical float, the surface shall be floated transversely by means of a
long-handled float. Care shall be taken not to work the crown out of the
pavement during the operation. After floating, any excess water and laitance
in excess of 1/8-inch thick shall be removed and wasted. Successive drags
shall be lapped one-half the length of the blade.

Straight-edge Testing and Surface Correction. After the pavement has been struck
off and while the concrete is still plastic, it shall be tested for trueness with a
Contractor furnished 16-foot straightedge swung from handles 3 feet longer than
one-half the width of the slab. The straightedge shall be held in contact with the
surface in successive positions parallel to the centerline and the whole area gone over
from one side of the slab to the other, as necessary. Advancing shall be in successive
stages of not more than one-half the length of the straightedge. Any excess water and
laitance in excess of 1/8-inch thick shall be removed from the surface of the
pavement and wasted. Any depressions shall be immediately filled with freshly
mixed concrete, struck off, consolidated, and refinished. High areas shall be cut
down and refinished. Special attention shall be given to assure that the surface across
joints meets the smoothness requirements of paragraph 5.02.I.3. Straightedge testing
and surface corrections shall continue until the entire surface is found to be free from
observable departures from the straightedge and until the slab conforms to the
required grade and cross section. The use of long-handled wood floats shall be
confined to a minimum; they may be used only in emergencies and in areas not
accessible to finishing equipment.
SURFACE TEXTURE
A.
The surface of the pavement shall be finished with either a brush or broom, or burlap
drag for all newly constructed concrete pavements. It is important that the texturing
equipment not tear or unduly roughen the pavement surface during the operation.
Any imperfections resulting from the texturing operation shall be corrected to the
satisfaction of the COTR.
B.
Brush or Broom Finish. If the pavement surface texture is to be a type of brush or
broom finish, it shall be applied when the water sheen has practically disappeared.
The equipment shall operate transversely across the pavement surface, providing
corrugations that are uniform in appearance and approximately 1/16 of an inch in
depth. It is important that the texturing equipment not tear or unduly roughen the
pavement surface during the operation. Any imperfections resulting from the
texturing operation shall be corrected.
C.
Burlap Drag Finish. If a burlap drag is used to texture the pavement surface, it shall
be at least 15 ounces per square yard. To obtain a textured surface, the transverse
threads of the burlap shall be removed approximately 1 foot from the trailing edge.
A heavy buildup of grout on the burlap threads produces the desired wide sweeping
longitudinal striations on the pavement surface. The corrugations shall be uniform in
appearance and approximately 1/16 of an inch in depth.
SAW CUT GROOVING
A.
Construct saw cut grooves where shown on the plans and according to the details in
the plans.

B.
Sawcut grooves shall not be closer than 3 inches or farther than 9 inches from
transverse paving joints. Grooves may be continued through longitudinal joints.
Grooves shall not be closer than 6 inches or farther than 18 inches from in-pavement
light fixtures. The Contractor shall protect in-pavement lights from damage during
the grooving and cleanup operation.
C.
Waste slurry created by saw cut grooving shall be cleaned up continuously during the
grooving operation. Waste material shall be disposed of in an approved manner.
Water material shall not be allowed to enter the airport storm or sanitary sewer
systems. After primary slurry removal and at the conclusion of each grooving shift,
flush the surface with water, then broom and vacuum the pavement surface to remove
all latents.
CURING
A.
Immediately after finishing operations are completed and marring of the concrete will
not occur, the entire surface of the newly placed concrete shall be cured in
accordance with the methods below. Failure to provide sufficient cover material, or
lack of water to adequately take care of both curing and other requirements, shall be
cause for immediate suspension of concreting operations. The concrete shall not be
left exposed for more than 1/2 hour during the curing period. Additionally, after the
initial sawcuts are completed the curing compound shall be reapplied to the sawcut
pavement. The following are alternate approved methods for curing concrete
pavements.
B.
Impervious Membrane Method. The entire surface of the pavement shall be sprayed
uniformly with white pigmented curing compound immediately after the finishing of
the surface and before the set of the concrete has taken place. The curing compound
shall not be applied during rainfall. Curing compound shall be applied by
mechanical sprayers under pressure at the rate of 1 gallon to not more than 150
square feet. The spraying equipment shall be of the fully atomizing type equipped
with a tank agitator. At the time of use, the compound shall be in a thoroughly mixed
condition with the pigment uniformly dispersed throughout the vehicle. During
application the compound shall be stirred continuously by mechanical means. Hand
spraying of odd widths or shapes and concrete surfaces exposed by the removal of
forms will be permitted. The curing compound shall be of such character that the
film will harden within 30 minutes after application. Should the film become
damaged from any cause, including sawing operations, within the required curing
period, the damaged portions shall be repaired immediately with additional
compound or other approved means. Upon removal of side forms, the sides of the
exposed slabs shall be protected immediately to provide a curing treatment equal to
that provided for the surface.
C.
Curing in Cold Weather. The concrete shall be maintained at a temperature of at
least 50 degrees F (10 degrees C) for a period of 72 hours after placing and at a
temperature above freezing for the remainder of the curing time. When concrete is
being placed and the air temperature may be expected to drop below 35 degrees F (2
degrees C), a sufficient supply of suitable insulated thermal blanketing material shall
be provided along the work. Any time the temperature may be expected to reach the

freezing point during the day or night, the material so provided shall be spread over
the pavement to a sufficient depth to prevent freezing of the concrete. The period of
time such protection shall be maintained shall not be less than 10 days. A minimum
of 3 days is required when high, early strength concrete is used. The Contractor shall
be responsible for the quality and strength of the concrete placed during cold
weather, and any concrete injured by frost action shall be removed and replaced at
the Contractor's expense.
501-4.15
REMOVING FORMS
A.
501-4.16
501-4.17
Unless otherwise specified, forms shall not be removed from freshly placed concrete
until it has hardened sufficiently to permit removal without chipping, spalling, or
tearing. After the forms have been removed, the sides of the slab shall be cured as
outlined in one of the methods indicated in paragraph 4.14. Major honeycombed
areas shall be considered as defective work and shall be removed and replaced in
accordance with paragraph 5.02.J. Any area or section so removed shall not be less
than 10 feet (3 m) in length nor less than the full width of the lane involved. When it
is necessary to remove and replace a section of pavement, any remaining portion of
the slab adjacent to the joints that is less than 10 feet (3 m) in length shall also be
removed and replaced.
SEALING JOINTS
A.
The joints in the pavement shall be sealed in accordance with Item P-605.
B.
To reduce dust and final cleanup efforts, slurry generated from sawcuts shall be
cleaned from the pavement using vacuum sweepers, brooms, flushing with water
and/or other methods before the slurry is allowed to dry.
PROTECTION OF PAVEMENT
A.
The Contractor shall protect the pavement and its appurtenances against both public
traffic and traffic caused by the Contractor's employees and agents. This shall
include watchmen to direct traffic and the erection and maintenance of warning signs,
lights, pavement bridges, crossovers, and protection of unsealed joints from intrusion
of foreign material, etc. Any damage to the pavement occurring prior to final
acceptance shall be repaired or the pavement replaced at the Contractor's expense.
The Contractor shall have available at all times, materials for the protection of the
edges and surface of the unhardened concrete. Such protective materials shall consist
of rolled polyethylene sheeting at least 4 mils thick of sufficient length and width to
cover the plastic concrete slab and any edges. The sheeting may be mounted on
either the paver or a separate movable bridge from which it can be unrolled without
dragging over the plastic concrete surface. When rain appears imminent, all paving
operations shall stop and all available personnel shall begin covering the surface of
the unhardened concrete with the protective covering.
The Contractor shall not use the new pavement as a material stockpile area for
loading of aggregate and other items requiring heavy equipment unless approved by
COTR.

Prior to commencement of paving operations, the Contractor shall submit for review
by the COTR a tabulation of elevations representing his interpretation of the paving
lane edge elevations. These elevations shall be presented to the nearest hundredth
(0.01) of a foot at intervals not exceeding twenty-five feet (25') on center.
REPAIR, REMOVAL, REPLACEMENT OF NEW SLABS
A.
General. New pavement slabs that are broken or contain cracks shall be removed and
replaced or repaired, as specified hereinafter at no cost to the Authority. Spalls along
joints shall be repaired as specified. Removal of partial slabs is not permitted.
Removal and replacement shall be full depth, shall be full width of the paving lane,
and the limit of removal shall be normal to the paving lane and to each original
transverse joint. The COTR will determine whether cracks extend full depth of the
pavement and may require cores to be drilled on the crack to determine depth of
cracking. Such cores shall be 4-inch diameter, shall be drilled by the Contractor and
shall be filled by the Contractor with a well consolidated concrete mixture bonded to
the walls of the hole with epoxy resin, using approved procedures. Drilling of cores
and refilling holes shall be at no expense to the Authority. All epoxy resin used in
this work shall conform to ASTM C-881, Type V.
B.
Slabs with Cracks through Interior Areas. Interior area is defined as that area more
than 6 inches from either adjacent original transverse joint. Slabs with any cracks
that extend into the interior area, regardless of direction, shall be treated by one of the
following procedures subject to the approval of the COTR.
1.
Cracks That Do Not Extend Full Depth of Slab. These cracks, and similar
cracks within the areas 6 inches each side of transverse joints, shall be
cleaned and then pressure injected with epoxy resin, ASTM C-881, Type IV,
Grade 1, using procedures as approved. Care shall be taken to assure that
the crack is not widened during epoxy resin injection. All epoxy resin
injection shall take place in the presence of the COTR.
2.
Cracks That Extend Full Depth of Slab. Where there is any full depth crack
at any place within the interior area, the full slab shall be removed and
replaced at no cost to the Authority.

Cracks Close To and Parallel To Transverse Joints. All cracks essentially parallel to
original transverse joints, extending full depth of the slab, and lying wholly within 6
inches either side of the joint shall be treated as specified hereinafter. Any crack
extending more than 6 inches from the transverse joint shall be treated as specified
above in subparagraph "Slabs With Cracks Through Interior Area." Any cracks
which do not extend full depth of the slab shall be treated as specified above in
subparagraph "Cracks That Do Not Extend Full Depth of Slab," and the original
transverse joint constructed as originally designed.
1.
Full Depth Cracks Present, Original Joint Not Opened. When the original
transverse joint has not opened, the crack shall be routed and sealed, and the
original transverse joint filled with epoxy resin as specified below. The
crack shall be sawed with equipment specially designed to follow random
cracks. The reservoir for joint sealant in the crack shall be formed by
routing to a depth of 3/4 inch, plus or minus 1/16 inch, and to a width of 5/8
inch, plus or minus 1/8 inch. Any equipment or procedure which causes
raveling or spalling along the crack shall be modified or replaced to prevent
such raveling or spalling. The joint sealant shall be a liquid sealant as
specified. Installation of joint sealant shall be as specified for sealing joints
or as directed. If the joint sealant reservoir has been sawed out, the reservoir
and as much of the lower saw cut as possible shall be filled with epoxy resin,
ASTM C-881, Type IV, Grade 2, thoroughly tooled into the void using
approved procedures. If only the original narrow saw cut has been made, it
shall be cleaned and pressure injected with epoxy resin, ASTM C-881, Type
IV, Grade 1, using approved procedures. If filler type material has been
used to form a weakened plane in the transverse joint, it shall be completely
sawed out and the saw cut pressure injected with epoxy resin, ASTM C-881,
Type IV, Grade 1, using approved procedures. Where a parallel crack goes
part way across paving lane and then intersects and follows the original
transverse joint which is cracked only for the remainder of the width, it shall
be treated as specified above for a parallel crack, and the cracked original
joint shall be prepared and sealed as originally designed.
2.
Full Depth Cracks Present, Original Transverse Joint Also Cracked. At a
transverse joint, if there is any place in the lane width where a parallel crack
and a cracked portion of the original joint overlap, the entire slab containing
the crack shall be removed and replaced for the full lane width and length.
Removal and Replacement of Full Slabs. Where it is necessary to remove full slabs.
The slab edges shall be sawed full depth just beyond the end of the dowels or tie
bars. All saw cuts shall be perpendicular to the slab surface. These joints shall then
be carefully sawed on the joint line to within 1 inch of the depth of the dowel. The
main slab shall be further divided by sawing full depth, at appropriate locations, and
each piece lifted out and removed. Suitable equipment shall be used to provide a
truly vertical lift, and approved safe lifting devices used for attachment to the slabs.
The narrow strips along doweled edges shall be carefully broken up and removed
using light, hand-held jackhammers, 30 lb or less, or other approved similar
equipment. Care shall be taken to prevent damage to the dowels, tie bars, or to

concrete to remain in place. The joint face below dowels shall be suitably trimmed
so that there is no abrupt offset in any direction greater than 1/2 inch and no gradual
offset greater than 1 inch when tested in a horizontal direction with a 12-foot
straightedge. No mechanical impact breakers, other than the above hand-held
equipment shall be used for any removal of slabs. If underbreak between 1-1/2 and 4
inches deep occurs at any point along any edge, the area shall be repaired as directed
before replacing the removed slab. Procedures will be directed before replacing the
removed slab. Procedures directed will be similar to those specified for surface
spalls, modified as necessary. If underbreak over 4 inches deep occurs, the entire
slab containing the underbreak shall be removed and replaced. Where there are no
dowels, or tie bars, on an edge, or where they have been damaged, dowels of the size
and spacing as specified for other joints in similar pavement shall be installed by
epoxy grouting them into holes drilled into the existing concrete using procedures as
specified. Original damaged dowels or tie bars shall be cut off flush with the joint
face. Protruding portions of dowels shall be painted and lightly oiled. All four edges
of the new slab shall thus contain dowels or original tie bars. Placement of concrete
shall be as specified for original construction. Prior to placement of new concrete,
the underlying material (unless it is stabilized) shall be re-compacted and shaped as
specified in the appropriate Section of these specifications. The surfaces of all four
joint faces shall be cleaned of all loose material and contaminants and coated with
double application of membrane forming curing compound as bond breaker. Care
shall be taken to prevent any curing compound from contacting dowels or tie bars.
The resulting joints around the new slab shall be prepared and sealed as specified for
original construction.

Repairing Spalls Along Joints. Where directed, spalls along joints of new slabs and
along parallel cracks used as replacement joints shall be repaired with polymer patch
material as specified in Section P-510 and as illustrated on the plans.
F.
Repairing Joint Overcuts into Existing Pavements. Where proposed joints do not
match existing joints, the Contractor shall not sawcut into existing payment more
than two inches horizontally. This overcut shall be filled with a COTR approved
epoxy material in accordance with the manufacturer’s instructions. Where proposed
joints match existing joints, the Contractor shall minimize the damage to the existing
joint sealing materials. Damaged joint seal material shall be removed and replaced to
the satisfaction of the COTR and Item P-605.

contained in ASTM D 3665. Areas such as thickened edges, with planned
variable thicknesses shall be excluded from sample locations.
a.
501-5.02
Cores shall be neatly cut with a core drill. The Contractor shall
furnish all tools, labor, and materials for cutting samples and filling
the cored hole. Core holes shall be filled by the Contractor with a
non-shrink grout approved by the COTR within one day after
sampling.
2.
Testing. The thickness of the cores shall be determined by the COTR by the
average caliper measurement in accordance with ASTM C 174.
3.
Acceptance. Acceptance of pavement for thickness shall be determined by
the COTR in accordance with paragraph 5.02.F.
F.
Partial Lots. When operational conditions cause a lot to be terminated before the
specified four tests have been made for the lot, the following procedure will be used
to adjust the lot size and the number of tests for the lot.
G.
Where three sublots have been produced, they shall constitute a lot. Where one or
two sublots have been produced, they shall be incorporated into the next lot or the
previous lot and the total number of sublots shall be used in the acceptance criteria
calculation, i.e., n=5 or n=6.
H.
Outliers. All individual flexural strength tests within a lot shall be checked for an
outlier in accordance with ASTM E 178, at a significance level of 5 percent. Outliers
shall be discarded, and the PWL shall be determined using the remaining test values.
ACCEPTANCE CRITERIA
A.
General. Acceptance will be based on the following characteristics of the completed
pavement:

Flexural strength will be evaluated for acceptance by the COTR in accordance with
paragraph 5.02.E. Thickness will be evaluated for acceptance by the COTR in
accordance with paragraph 5.01.F. Smoothness will be evaluated by the COTR in
accordance with paragraph 5.02.I.3.
C.
Acceptance for flexural strength will be based on the criteria contained in accordance
with paragraph 5.02.I.1. Acceptance for thickness will be based on the criteria
contained in paragraph 5.02.I.2. Acceptance for smoothness will be based on the
criteria contained in paragraph 5.02.I.3. Acceptance for grade will be based on the
criteria contained in paragraph 5.02.I.5.
D.
The COTR may at any time, not withstanding previous plant acceptance, reject and
require the Contractor to dispose of any batch of concrete mixture which is rendered
unfit for use due to contamination, segregation, or improper slump. Such rejection
may be based on only visual inspection. In the event of such rejection, the Contractor
may take a representative sample of the rejected material in the presence of the
COTR, and if it can be demonstrated in the laboratory, in the presence of the COTR,
that such material was erroneously rejected, payment will be made for the material at
the contract unit price.
E.
Flexural Strength. Acceptance of each lot of in-place pavement for flexural strength
shall be based on the percentage of material within specification limits (PWL). The
PWL plan considers the variability (standard deviation) of the material and the testing
procedures, as well as the average (mean) value of the test results. The standard
deviation shall be determined from the Contractor's own data or from historic data. If
a material with high variability is produced, then a higher average strength must be
maintained in order to achieve a PWL of 90 percent or more.
F.
Pavement Thickness. Acceptance of each lot of in-place pavement shall be based on
the percentage of material within specification limits. The standard deviation shall be
determined from the Contractor's own data or from historic data. If a pavement with
a high thickness variability is placed, then a higher average thickness must be
maintained in order to achieve a PWL of 90 percent or more.
G.
Percentage of Material Within Limits (PWL). The percentage of material within
limits shall be determined in accordance with procedures specified in Section 5.03.
H.
The lower specification limit (L) for flexural strength and thickness shall be:

Flexural Strength. If the PWL of the lot equals or exceeds 90 percent for
flexural strength, the lot shall be acceptable. Acceptance and payment for
the lot shall be in accordance with Paragraph 8.01.
2.
Thickness. If the PWL of the lot equals or exceeds 90 percent for thickness,
the lot shall be acceptable. Acceptance and payment for the lot shall be in
accordance with Paragraph 8.01.
3.
Smoothness. As soon as the concrete has hardened sufficiently, the
pavement surface shall be tested with a 16-foot straightedge or other
specified device. Surface smoothness deviations shall not exceed 1/4 inch
from a 16-foot straightedge placed in any direction, including placement
along and spanning any pavement joint edge.
4.
Areas in a slab showing high spots of more than 1/4 inch but not exceeding
1/2 inch in 16 feet shall be marked and immediately ground down with an
approved grinding machine to an elevation that will fall within the tolerance
of 1/4 inch or less. Where the departure from correct cross section exceeds
1/2 inch, the pavement shall be removed and replaced at the expense of the
Contractor when so directed by the COTR.
5.
Grade. An evaluation of the surface grade shall be made by the COTR for
compliance to the tolerances contained below.
6.
Lateral Deviation. Lateral deviation from established alignment of the
pavement edge shall not exceed plus or minus 0.10 foot in any lane.
7.
Vertical Deviation. Vertical deviation from established grade shall not
exceed plus or minus 0.04 foot at any point.
8.
Edge Slump. When slip-form paving is used, not more than 15 percent of
the total free edge of each 500 feet of pavement, or fraction thereof, shall
have an edge slump exceeding 1/4-inch, and none of the free edge of the
pavement shall have an edge slump exceeding 3/8-inch. (The total free edge
of 500 feet of pavement will be considered the cumulative total linear
measurement of pavement edge originally constructed as nonadjacent to any
existing pavement; i.e., 500 feet of paving lane originally constructed as a
separate lane will have 1,000 feet of free edge, 500 feet of fill-in lane will
have no free edge, etc.) The area affected by the downward movement of
the concrete along the pavement edge shall be limited to not more than 18
inches from the edge. When excessive edge slump cannot be corrected
before the concrete has hardened, the area with excessive edge slump shall
be removed and replaced at the expense of the Contractor when so directed
by the COTR.

position and alignment. The maximum permissible tolerance on dowel bar
alignment in each plane, horizontal and vertical, shall not exceed 2 percent
or 1/4 inch per foot of a dowel bar.
Removal and Replacement of Concrete. Any area or section of concrete that is
removed and replaced shall be removed and replaced back to planned joints. The
Contractor shall replace damaged dowels and the requirements for doweled
longitudinal construction joints in paragraph 4.10 shall apply to all contraction joints
exposed by concrete removal.
METHOD OF ESTIMATING PERCENTAGE OF MATERIAL WITHIN SPECIFICATION
LIMITS (PWL)
A.
501-5.03.1
IA1003
July 9, 2010
GENERAL. When the specifications provide for material to be sampled and tested
on a statistical basis, the material will be evaluated for acceptance in accordance with
this section. All test results for a lot will be analyzed statistically, using procedures to
determine the total estimated percent of the lot that is within specification limits.
This concept, termed percent within limits (PWL), is a statistically based evaluation
method, whereby the PWL is computed on a lot basis, using the average (X) and
standard deviation (Sn) of the specified number (n) of sublot tests for the lot and the
specification tolerance limits (L for lower and U for upper) for the particular
acceptance parameter. From these values, the respective Quality index(s) (QL for
Lower Quality Index and/or QU for Upper Quality Index) is computed and the PWL
for the specified n is determined from Table 4.
METHOD FOR COMPUTING PWL
The computational sequence for computing the PWL is as follows:
A.
Divide the lot into n sublots in accordance with the acceptance requirements of the
specification.
B.
Locate the sampling position within the sublot in accordance with the random
sampling requirements of the specification.
C.
Make a measurement at each location, or take a test portion and make the
measurement on the test portion in accordance with the testing requirements of the
specification.
D.
Average all sublot values within the lot to find X by using the following formula:
X = (x1 + x2 + x3 + . . .xn) / n
Where:
X = Average of all sublot values within a lot
x1, x2 = Individual sublot values

Washington Dulles International Airport
Repair In-Pavement High Speed Taxiway Centerline
Light Trench, Runway 1R-19L
IA1003
July 9, 2010
n = Number of sublots
E.
Find the standard deviation Sn by use of the following formula:
Sn = [(d12 + d22 + d32 + . . .dn2) / n-1]1/2
Where:
Sn = standard deviation of the number of sublot values in the set
d1, d2 = deviations of the individual sublot values X1, X2 . . . from the average value
X
that is: d1 = (x1 - X), d2 = (xn - X) . . dn = (xn - X)
n = number of sublots
F.
For single sided specification limits (i.e., L only), compute the Lower Quality Index
QL by use of the following formula:
QL = (X - L) / Sn
Where:
L = specification lower tolerance limit
Estimate the percentage of material within limits (PWL) by entering Table 4 with
QL, using the column appropriate to the total number (n) of measurements. If the
value of QL falls between values shown on the table, use the next higher value of
PWL.
G.
For double sided specification limits (i.e. L and U), compute the Quality Indexes QL
and QU by use of the following formulas:
QL = (X - L) / Sn and QU = (U - X) / Sn
Where:
L and U = specification lower and upper tolerance limits
Estimate the percentage of material between the lower (L) and upper (U) tolerance
limits (PWL) by entering Table 4 separately with QL and QU, using the column
appropriate to the total number (n) of measurements, and determining the percent of
material above PL and percent of material below PU for each tolerance limit. If the
values of QL fall between values shown on the table, use the next higher value of PL
or PU. Determine the PWL by use of the following formula:
PWL = (PU + PL) - 100

PLACING REINFORCEMENT
All reinforcement shall be accurately placed, as shown on the plans, and shall be firmly held
in position during concreting. Bars shall be fastened together at a minimum of 50% of
intersections. The reinforcement shall be supported by approved metal chairs. Shop
drawings, lists, and bending details shall be supplied by the contractor for structures
including, but not limited to, inlets and other structures where required by the COTR. Form
release agents shall not be allowed to come in contact with reinforcing steel.
610-3.10
EMBEDDED ITEMS
Before placing concrete, any items that are to be embedded shall be firmly and securely
fastened in place as indicated. All such items shall be clean and free from coating, rust, scale,
oil, or any foreign matter. The embedding of wood shall be avoided. The concrete shall be
spaded and consolidated around and against embedded items.
610-3.11
PLACING CONCRETE
All concrete shall be placed during daylight, unless otherwise approved. The concrete shall
not be placed until the depth and character of foundation, the adequacy of forms and false
work, and the placing of the steel reinforcing have been approved. Concrete shall be placed
as soon as practical after mixing and in no case later than 1 hour after water has been added to
the mix. The method and manner of placing shall be such to avoid segregation and
displacement of the reinforcement. Troughs, pipes, and chutes shall be used as an aid in
placing concrete when necessary. Dropping the concrete a distance of more than 5 feet, or
depositing a large quantity at one point, will not be permitted. Concrete shall be placed upon
clean, damp surfaces, free from running and standing water, or upon properly consolidated
soil. Concrete shall not be placed on snow, ice, or frozen subgrade.
The concrete shall be compacted with suitable mechanical vibrators operating within the
concrete. When necessary, vibrating shall be supplemented by hand spading with suitable
tools to assure proper and adequate compaction. Vibrators shall be manipulated so as to work
the concrete thoroughly around the reinforcement and embedded fixtures and into corners and
angles of the forms.
The vibration at any joint shall be of sufficient duration to accomplish compaction but shall
not be prolonged to the point where segregation occurs. Concrete deposited under water shall
be carefully placed in a compact mass in its final position by means of a tremie, a closed
bottom dump bucket, or other approved method and shall not be disturbed after being
deposited.
610-3.12
CONSTRUCTION JOINTS
When the placing of concrete is suspended, necessary provisions shall be made for joining
future work before the placed concrete takes its initial set. For the proper bonding of old and
new concrete, such provisions shall be made for grooves, steps, keys, dove tails, reinforcing
bars or other devices as may be prescribed. The work shall be arranged so that a section
begun on any day shall be finished during daylight of the same day. Before depositing new
concrete on or against concrete which has hardened, the surface of the hardened concrete shall
be cleaned by a heavy steel broom, roughened slightly, wetted, and covered with a neat

EXPANSION JOINTS
Expansion joints shall be constructed at such points and of such dimensions as may be
indicated on the drawings. The premolded filler shall be cut to the same shape as that of the
surfaces being joined. The filler shall be fixed firmly against the surface of the concrete
already in place using an adhesive or other method approved by the COTR in such manner
that it will not be displaced when concrete is deposited against it.
610-3.14
DEFECTIVE WORK
Any defective work disclosed after the forms have been removed shall be immediately
removed and replaced. If any dimensions are deficient, or if the surface of the concrete is
bulged, uneven, or shows honeycomb, which in the opinion of the COTR cannot be repaired
satisfactorily, the entire section shall be removed and replaced at the expense of the
Contractor.
610-3.15
SURFACE FINISH
All exposed concrete surfaces shall be true, smooth, free from open or rough spaces,
depressions, or projections. The concrete in horizontal plane surfaces shall be brought flush
with the finished top surface at the proper elevation and shall be struck off with a straightedge
and floated. Mortar finishing shall not be permitted, nor shall dry cement or sand-cement
mortar be spread over the concrete during the finishing of horizontal plane surfaces.
When directed, the surface finish of exposed concrete shall be a rubbed finish. If forms can
be removed while the concrete is still green, the surface shall be pointed and wetted and then
rubbed with a wooden float until all irregularities are removed. If the concrete has hardened
before being rubbed, a carborundum stone shall be used to finish the surface. When
approved, the finishing can be done with a rubbing machine.
610-3.16
CURING AND PROTECTION
All plain or reinforced structural Portland concrete shall be properly cured and protected by
the Contractor. The work shall be protected from the elements, flowing water, and from
defacement of any nature during the building operations. The concrete shall be cured as soon
as it has sufficiently hardened by covering with an approved material. Water-absorptive
coverings shall be thoroughly saturated when placed and kept saturated for a period of at least
3 days. All curing mats or blankets shall be sufficiently weighted or tied down to keep the
concrete surface covered and to prevent the surface from being exposed to currents of air.
Where wooden forms are used, they shall be kept wet at all times until removed to prevent the
opening of joints and drying out of the concrete. Traffic shall not be allowed on concrete
surfaces for 7 days after the concrete has been placed.

an operational error, such as permitting pressure water to dwell in one location for an
extensive time, the Contractor shall repair said damage without compensation.
621-3.3
Paint removal shall be defined as the removal of at least 90 percent of the existing
marking. The 90 percent removal shall be determined by the COTR by visual inspection.
In addition to the visual determination, the 90 percent removal level is defined such that
there shall not be any remaining surface of undisturbed paint or individual contiguous
areas larger than one square inch where the surface of the pavement material is not
clearly exposed.
621-3.4
The method used shall not materially change the structural integrity of the pavement.
Any damage caused by the Contractor’s operations shall be corrected at the Contractor’s
