Provided, however, that the negative tolerance for wearing course shall not be permitted in

conjunction with the positive tolerance for base course, if the thickness of the former is thereby

reduced by more than 6 mm for flexible pavements and 5 mm for concrete pavements.

For checking compliance with the above requirement for subgrade, sub-base and base

courses, measurements of the surface levels shall be taken on a grid of points placed at

10 m longitudinally and 2.5 m transversely. For any 10 consecutive measurements taken

longitudinally or transversely, not more than one measurement shall be permitted to exceed

the tolerance as above, this one measurement being not in excess of 5 mm above the

permitted tolerance.

For checking the compliance with the above requirement for bituminous wearing courses

and concrete pavements, measurements of the surface levels shall be taken on a grid of

points spaced at 6.25 m along the length and at 0.5 m from the edges and at the centre of

the pavement. In any length of pavement, compliance shall be deemed to be met for the final

road surface, only if the tolerance given above is satisfied for any point on the surface.

1802.5 Rectification

Where the surface regularity of subgrade and the various pavement courses fall outside the

specified tolerances, the Contractor shall be liable to rectify these in the manner described

below and to the satisfaction of the Engineer.

i) Subgrade : Where the surface is high, it shall be trimmed and suitably

compacted. Where the same is low, the deficiency shall be corrected by

scarifying the lower layer and adding fresh material and recompacting to

Section 1800 Quality Control

the required density. The degree of compaction and the type of material

to be used shall conform to the requirements of Section

ii) Granular Sub-base : Same as at (i) above, except that the degree of

compaction and the type of material to be used shall conform to the

requirements of Section

iii) Lime/Cement Stabilized Soil Sub-base : For lime/cement treated

materials where the surface is high, the same shall be suitably trimmed

while taking care that the material below is not disturbed due to this

operation. However, where the surface is low, the same shall be

corrected as described hereinbelow.

For cement treated material, when the time elapsed between detection

of irregularity and the time of mixing of the material is less than 2 hours,

the surface shall be scarified to a depth of 50 mm supplemented with

freshly mixed materials as necessary and recompacted to the relevant

specification. When this time is more than 2 hours, the full depth of

the layer shall be removed from the pavement and replaced with fresh

material to Specification. This shall also apply to lime treated material

except that the time criterion shall be 3 hours instead of 2 hours.

iv) Water Bound Macadam/Wet Mix Macadam Sub-base/Base : Where

the surface is high or low, the top 75 mm shall be scarified, reshaped with

added material as necessary and recompacted as per requirements of

v) Bituminous Constructions : For bituminous construction other than

wearing course, where the surface is low, the deficiency shall be

corrected by adding fresh material over a suitable tack coat if needed

and recompacting to specifications. Where the surface is high, the full

depth of the layer shall be removed and replaced with fresh material

and compacted to specifications.

For wearing course, where the surface is high or low, the full depth of the

layer shall be removed and replaced with fresh material and compacted

to specifications. In all cases where the removal and replacement of a

bituminous layer is involved, the area treated shall be not less than 5 m

in length and not less than 3.5 m in width.

vi) Dry Lean Concrete Sub-base/Roller Compacted Cement

Concrete : The defective length of the course shall be removed to

full depth and replaced with material conforming to Section 1500, as

applicable. The area treated shall be at least 3 m long, not less than

1 lane wide and extend to the full depth. Before relaying the course,

the disturbed subgrade or layer below shall be corrected by levelling,

watering and compaction.

vii) Cement Concrete Pavement : The defective areas having surface

irregularity exceeding the specified limits may be rectified by bump

Quality Control Section

cutting or scabbling or grinding using approved equipment. When

required by the Engineer, areas which have been reduced in level by

the above operation(s) shall be retextured in an approved manner either

by cutting grooves (5 mm deep) or roughening the surface by hacking

the surface. If high areas in excess of 6 mm or low areas in excess of

3 mm occur, exceeding the permitted numbers and if the Contractor

cannot rectify, the slab shall be demolished and reconstructed by the

Contractor at his own expense and in no case the area removed shall

be less than the full width of the lane in which the irregularity occurs

and full length of the slab.

If deemed necessary by the Engineer, any section of the slab which

deviates from the specified levels and tolerances, shall be demolished

and reconstructed by the Contractor at his own expense.

1803 Quality Control Tests

The materials supplied and the works carried out by the Contractor shall conform to the

specifications prescribed in relevant Sections of these Specifications.

For ensuring the requisite quality of construction, the materials and works shall be subjected

to quality control tests, as described hereinafter. The testing frequencies set forth are the

desirable minimum and the Engineer shall have the full authority to require the Contractor

to carry out additional tests as frequently as he may deem necessary, to ensure that the

materials and works comply with the appropriate specifications. However, the number of

tests recommended in Tables 1800.4 to 1800.55 may be reduced at the discretion of the

Engineer if it is felt that consistency in the quality of materials can still be maintained.

Test procedures for the various quality control tests are indicated in the respective Sections

of these Specifications or for certain tests within this Section. Where no specific testing

procedure is mentioned, the tests shall be carried out as per sound engineering practice or

as per directions of the Engineer.
