installed binder course and a new surface course if both courses are placed in
the same working day. The installation shall be as per the latest MDOT
Specifications. The distributor truck shall be capable of applying bituminous
material uniformly at various widths and maintained in a leak free condition. The
type and grade of bituminous material shall be submitted to the Town of Greene

B. When the air temperature in the shade at the work area is less than forty
degrees Fahrenheit (40 F).
C. When the Highway Foreman or Town Manager feels that the weather or
surface conditions prevent the proper handling, placing and finishing of the mix.
D. Base and surface courses shall not be placed earlier or later than the dates, or
minimum temperatures specified in the most recent MDOT Specifications.

mix asphalt pavements at lower atmospheric temperatures than those specified,
or extend the paving dates of the paving season if it is in the best interests of the
Town of Greene to complete a project. In the event showers occur during the
paving operations, the Contractor may be allowed to use whatever mix is in
transit at the time the shower begins. The Contractor shall dispose of all material
that becomes unusable due to weather conditions.
PAVING OPERATIONS:
A. The Contractor shall perform the work of placing the HMA so that the full width
of the street is paved at the end of each day of operation with no exposed
longitudinal joints in excess of 10'. Where curb is in place and a reasonable
gutter cross section and grade exists, the Contractor will be required to extend
the new pavement to the existing curb. The Contractor shall pave the
approaches of side streets as directed by the Highway Foreman or Town
Manager. The finished appearance of the surface shall be uniform and smooth.
Any mixture that becomes loose, broken, contaminated with dirt, or in any way
defective, prior to the acceptance of the work, shall be removed and replaced
with fresh, hot material, which shall be immediately compacted to conform to the
surrounding area.
B. Any area exceeding one square foot in area, containing an excess of bitumen
causing the surface to be tacky or "bleed" shall be removed and replaced at the
Contractor’s expense.

workmanship. The Contractor shall completely remove and replace any material
displaying evidence of poor quality or substandard workmanship within 1 year

Job mix formula shall be an MDOT approved mix in compliance with all
requirements and specifications listed in the most current MDOT Standard
Specification Section 401. The Contractor shall submit for approval, a new jobmix formula each time a change in aggregate source or a change in Performance
Graded Asphalt Binder (PGAB) is proposed. When unsatisfactory results or other
conditions make it necessary, the Highway Foreman or Town Manager may
request a new job-mix formula.
BITUMINOUS PAVER:
A. Pavers used on Town of Greene projects shall be of highway class, selfcontained, self-propelled. pavers capable of placing HMA pavement over
the full width of the mainline travel way with a minimum 10’ foot minimum
main screed with power activated extensions. Pavers shall be in
compliance with all MDOT specifications. The Highway Foreman or Town
Manager may approve the use of smaller pavers on smaller projects such
as small parking lots or some trench paving.
B.
When HMA pavement is placed on major arterials, or when
directed by the Highway Foreman, the Contractor shall use a paver
equipped with automatic grade or slope controlled screed. The controls
shall automatically adjust the screed to increase or decrease the mat
thickness to compensate for irregularities in the preceding course. The
Contractor shall operate the paver producing straight passes when
possible and a visually uniform wear surface in compliance with the most
current MDOT specifications.

operations to be inspected and approved. Any paver found worn or
defective either before or during its use shall be replaced or repaired to

C. When paving on sidewalks or similar surfaces, a smaller roller properly
sized for the type of work shall be provided and used.
SPREADING AND FINISHING:
A. The mixture shall be laid upon an approved surface, spread and struck off to
the grade and elevation established. Bituminous pavers shall be used to
distribute the mixture either over the entire width or over such partial width as
may be practicable. During placing operations, pavers shall be operated at a
speed so as to provide as continuous as possible placement of the mixture as
normally produced by the plant, regardless of haul distance.
B. On small areas, or where irregularities or unavoidable obstacles make the use
of mechanical spreading and finishing equipment impracticable, the mixture shall
be spread, raked and luted with hand tools to the required compacted thickness.
Mixture dumped directly from the truck shall be completely re-handled to the work
area to provide a uniform density after compaction.
C. When production of the mixture can be maintained and when practical, pavers
may be used in echelon to place the surface course in adjacent lanes. On roads
opened to two-way traffic, the placement of each course shall be completed over
the full width of the travel way section being paved on each day’s work unless
otherwise approved.
COMPACTION:
A. HMA placed on Town of Greene projects shall immediately be compacted in a
method complying with the requirements listed in the most current MDOT
Standard Specification.
B. Care shall be exercised in rolling not to displace the line and grade of the
edges of the bituminous mixture. Any new pavement that shows obvious
cracking, checking, or other defect shall be removed and replaced as directed by
the Highway Foreman or Town Manager at no cost to the Town of Greene.
C. To prevent adhesion of the mixture to the rollers, the wheel shall be kept
properly moistened with water or water mixed with very small quantities of
detergent or other approved material. Excess liquid or oil will not be permitted.
D. Along forms, curbs, headers, catch basins, walls, and other places not
accessible to the rollers, the mixture shall be thoroughly compacted with
mechanical vibrating compactors. Hand tamping will be permitted only for areas
inaccessible to other compaction equipment. On depressed areas, a trench roller
may be used or cleated compression strips may be used under the roller to
transmit compression to the depressed area.
JOINTS:
A. Joints shall be constructed in a manner complying with the requirements
listed in the most current MDOT Standard Specification. The paver shall
always maintain a uniform head of HMA during the joint construction.
Transverse joints of the wearing course shall be straight and neatly
trimmed. The edge of the layer shall be constructed vertical and rollers or
traffic shall not pass over the unprotected end of freshly laid mixture
unless authorized by the Highway Foreman or Town Manager.
B. Feather joints will not normally be permitted without the permission of the
Highway Foreman or Town Manager.
C. The Contractor shall apply a uniform coating of emulsified asphalt to the
vertical face of all joints immediately before placing the adjacent mat. The
Contractor shall use an approved spray apparatus designed for covering a
narrow surface. Application of this material by a brush may be approved for small
surfaces, or in the event of a malfunction of the spray apparatus, but for a period
of not more than one working day.
