Schedule for Tests
2.1
The Concessionaire shall, not later than 30 (thirty) days prior to the likely
completion of work [2-Laning reconstruction], notify the Independent Consultant and
PIU-KSHIP of its intent to subject the Project Highway to Tests, and not later than 10
(ten) days prior to the actual date of Tests, furnish to the Independent Consultant and
PIU-KSHIP a detailed inventory and particulars of all works and equipments forming
part of Project Highway.
2.2
The Concessionaire shall notify the Independent Consultant of its readiness to subject
the Project Highway to Tests at anytime after 10(ten) days from the date of such
notice, and upon receipt of such notice, the independent Consultant shall, in
consultation with the Concessionaire, determine the date and time for each Test and
notify the same to PIU-KSHIP who may designate its representative to witness the
Tests. The Independent Consultant shall thereupon conduct the Tests itself or cause
any of the Tests to be conducted in accordance with Article 16 and this Schedule-J.
3.
Tests
Visual and physical Tests: The Independent Consultant shall conduct a visual and
physical check of Project Highway to determine that all works and equipment forming part
thereof conform to the provisions of this Agreement.
Test Drive: The Independent Consultant shall take test drive of the Project Highway by a
Car and a fully loaded Truck to determine that the quality of service conforms to the
provisions of this Agreement.
Riding quality Test: Riding quality of each lane of the carriageway shall be checked
with the help of a calibrated integrator as mentioned at annexure A of this Schedule.
Pavement Composition Test: the thickness and composition of the pavement structure
shall be checked on a sample basis by digging pits to determine conformity of such pavement
structure with Specifications and Standards. The sample shall consists of one pit in each
direction of travel to be chosen at random in each stretch of 5 (five) kilometers of the Project
Highway. The first pit for the sample shall be selected by the Independent Consultant through
an open draw of lots and every fifth kilometer from such first pit shall from part of the sample
for this pavement quality Test.
Cross-section Test: the cross-sections of the Project Highway shall be checked on a
sample basis through physical measurements of their dimensions for determining the
conformity thereof with Specifications and Standards. For the road portion, the sample shall
consists of one spot to be selected at random in each stretch of 1 (one) kilometer of the
Project Highway. The first spot shall form part of the sample which shall selected by the
Independent Consultant through an open draw of lots and the spots located at every one
kilometer from such first spot shall form part of the sample. For the bridge portion, one spot
shall be selected at random by the Independent Consultant in each span of the bridge.
Structural Test for bridges: All major and minor bridges constructed by the
Concessionaire shall be subjected to the Rebound Hammer and Ultrasonic Pulse Velocity
tests, to be conducted in accordance with the procedure described in Special Report No. 14;

spot in every span, to be chosen random by the Independent Consultant.
Environment audit: The Independent Consultant shall carry out a check to determine
conformity of the Project Highway with the environment requirements set forth in Applicable
Laws and Applicable Permits.
Safety Review: Safety audit of the Project Highway shall have been undertaken by the
Safety Consultant as set forth in Schedule-L and on the basis of such audit, the Independent
Consultant shall determine conformity of the Project Highway with the provisions of this
Agreement.
Completion / Provisional Certificate
Upon successful completion of Tests, the Independent Consultant shall issue the
completion Certificate or the Provisional Certificate, as the case may be, in
accordance with the provisions of Article 16.4.

TEST PROCEDURE FOR MEASURING ROUGHNESS INDEX OF THE RIDING
SURFACE OF A FLEXIBLE PAVEMENT
EQUIPMENT- Bump Integrator Fitted in a Vehicle.
Test Procedure:
The following test procedure shall be adopted for the test.
1)
Check that the installation and operation of the equipment is in order and meets the
requirements prescribed in its operational manual. The tyre pressure of wheels should
be prescribed.
2)
The instrument shall be calibrated prior to its use for measurement as prescribed in its
operational manual.
3)
The operators shall familiarizes themselves with the Bump Integrator & other
equipment associated with its operation using its Test Model before commencing a
survey.
4)
Generally a speed varying between 30 km/hour +/– 5 km/hour shall be maintained
during measurements. The readings shall be taken for each carriageway
independently.
5)
The equipment shall run on two lane in both the directions once and the average to
two values taken for its roughness index.
6)
Pavement unevenness / roughness of two lane carriageway shall be obtained from the
average of the values of the two lane recorded.
7)

Annexure – B
LOAD TESTING OF A BRIDGE SUPERSTRUCTURE
The load test shall be carried out to atleast one full superstructure check and establish the
serviceability and working strength of the superstructure.
1
Test Load
The “Test Load” is the equivalent static load equal to the impacted working design Live Load
(applied in addition to all dead loads) placed for maximum effect (bending moment, shear,
deflection, etc. as the case may be) and applied either through an appropriate test loading
truck or through loading platforms resting on tyre contact area plates simulating and actual
areas of wheels.
2
Load Application and Testing Procedure
i.
Fix deflection gauges (supported on unyielding supports) under the superstructure,
just touching its soffit, at the pre-marked critical ‘Points’.
ii.
Apply the test load in five equal increments (including the weight of platforms of
trucks in the first increment), allowing about two hours in between completion of one
load increment and commencement of the next. About an hour after completing a load
increment, note the deflections and any crack patterns together with maximum crack
widths.
iii.
After measuring the deflections, etc. one hour after applying the fifth increment, i.e.
the final load increment, keep the test load maintained for about 24 hours and again
measure the deflections and crack widths (if any)
iv.
Remove the test load in five equal decrements, allowing about two hours in between
completion of one load decrement and commencement of the next. Note the
deflections and crack widths (if any) at the end of each load decrement.
v.
Note the deflection and crack widths (if any – 24 hours after removal of the test load
in order to see whether the recovery is completed or there is any residual deflection,
etc.
3
Acceptance Criteria
i.
Increase and decrease in deflections at a point shall follow a linear relations, with
actual deflection not exceeding the theoretically estimated ones by more than 10%.
ii.
The maximum crack width in reinforced concrete shall not exceed 0.25 mm to 0.30
mm (but no cracks in case of prestressed concrete).
iii.
The deflection at the end of the 24 hours of maintaining the test load shall not exceed
the corresponding values at the start of this 24 hours period by 5% and
iv.
The residual deflection at any point 24 hours after compete unloading shall not exceed
10% of the maximum observed deflection at the point (i.e. recovery: 90% or more);
