Construction Operations :-

Preparation of Sub-grade

Immediately prior to the laying of sub-base, the subgrade already finished shall be prepared by removing all vegetation and

other extraneous matter, lightly sprinkled with water, rolled with two passes of 80-100 kN smooth wheeled roller.

Spreading and Compacting

The sub-base material of the grading specified in the Contract shall be spread on the prepared sub grade with the help of a

motor grader of adequate capacity, its blade having hydraulic controls suitable for initial adjustment and for maintaining the

required slope and grade during the operation, or other means as approved by the Engineer.

Manual mixing shall be permitted only where the width of laying is not adequate for mechanical operations as in small sized

jobs. The equipment used for mix-in-place construction shall be a rotavator or similar approved equipment capable of mixing

the material to the desired degree. If so desired by the Engineer, trial runs with the equipment shall be carried out to

establish its suitability for the work.

Moisture content of the loose material shall be checked in accordance with IS:2720 (Part 2) and suitably adjusted by

sprinkling additional water from a truck mounted or trailer mounted water tank and suitable for applying water uniformly and

at controlled quantities to variable widths of surface or other means approved by the Engineer so that, at the time of

compaction, it is from 1 per cent above to 2 per cent below the optimum moisture content corresponding to IS: 2720 (Part 8).

While adding water, due allowance shall be made for evaporation losses. After water has been added, the material shall be

processed by mechanical or other approved means like disc harrows, rotavators until the layer is uniformly wet.

Immediately after spreading the mix, rolling shall be done by an approved roller. If the thickness of the compacted layer does

not exceed 100 mm, a smooth wheeled roller of 80 to 100 kN weight may be used. For a compacted single layer upto 200 mm

the compaction shall be done with the help of a vibratory roller of minimum 80 to 100 kN static weight capable of achieving

the required compaction. Rolling shall commence at the lower edge and proceed towards the upper edge longitudinally for

portions having unidirectional cross fall or on super elevation. For carriageway having cross fall on both sides, rolling shall

commence at the edges and progress towards the crown.

Each pass of the roller shall uniformly overlap not less than one-third of the track made in the preceding pass. During rolling,

the grade and cross fall (camber) shall be checked and any high spots or depressions which become apparent, corrected by

removing or adding fresh material. The speed of the roller shall not exceed 5 km per hour.

Rolling shall be continued till the density achieved is at least 98 percent of the maximum dry density for the material

determined as per IS:2720 (Part 8). The surface of any layer of material on completion of compaction shall be well closed, free

from movement under compaction equipment and from compaction planes, ridges, cracks or loose material. All loose,

segregated or otherwise defective areas shall be made good to the full thickness of layer and re-compacted.

a) Flexible pavement ±10 mm

b) Concrete pavement ±6 mm

3) Base-course for flexible pavement ±6 mm

a) Bituminous Base/Binder course

i) Machine laid ±10 mm

ii) Manually laid ±15 mm

4) Wearing course for flexible pavement

a) Machine laid ±6 mm

b) Manually laid ±10 mm

5) Cement concrete pavement ±5 mm

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 the following limits:

• 4 mm for bituminous wearing course of thickness 40 mm or more

• 3 mm for bituminous wearing course of thickness less than 40 mm

• 5 mm for concrete pavement slab

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

surface levels shall be taken on a grid of points placed at 6.25 m longitudinally and 3.5 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.

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 as per

specifications. Where the surface is high, the extra thickness in the affected 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 not be less than 5 m in

length and not less than 3.5 m in width.

repaired and made good with the suitable material. The existing surface shall be scarified and re-shaped to the required grade and

camber before spreading the coarse aggregate for Wet mix macadam.

Preparation of Mix

Wet Mix Macadam should be prepared in an approved mixing plant of suitable capacity having provision for controlled addition of

water and forced/positive mixing arrangement like pugmill or pan type mixer of concrete batching plant. For small quantity of wet

mix work, the Engineer may permit the mixing to be done in concrete mixers.

should be uniformly wet and no segregation should be permitted.

Spreading of mix

Immediately after mixing, the aggregates shall be spread uniformly and evenly upon the prepared subgrade/sub-base/base in

required quantities. In no case should these be dumped in heaps directly on the area where these are to be laid nor shall their

hauling over a partly completed stretch be permitted.

The mix may be spread either by a paver finisher or motor grader or as per instruction of Engineer-in-Charge and/or his authorized

representative. For portions where mechanical means cannot be used, manual means as approved by the Engineer shall be used.

aggregate as may be required. The layer may be tested by depth blocks during construction. No segregation of layer and fine

particles should be allowed. The aggregates as spread should be of uniform gradation with no pockets of fine materials.

After the mix has been laid to the required thickness, grade and crossfall/camber the same shall be uniformly compacted, to the full

depth with suitable roller. If the thickness of single compacted layer does not exceed 100 mm, smooth wheel roller of 80 to 100 kN

weight may be used. For a compacted single layer upto 200 mm, the compaction shall be done with the help of vibratory roller of

minimum static weight of 80 to 100 kN or equivalent capacity roller. The speed of the roller shall not exceed 5 km/h.

In portions having unidirectional cross fall/superelevation, rolling shall commence from the lower edge and progress gradually

towards the upper edge. Thereafter, roller should progress parallel to the centre line of the road, uniformly over-lapping each

preceding track by at least one third width until the entire surface has been rolled. Alternate trips of the roller shall be terminated in

stops at least 1 m away from any preceding stop.

In portions in camber, rolling should begin at the edge with the roller running forward and backward until the edges have been

firmly compacted. The roller shall then progress gradually towards the centre parallel to the centre line of the road uniformly

overlapping each of the preceding track by at least one-third width until the entire surface has been rolled.

Any displacement occurring as a result of reversing of the direction of a roller or from any other cause shall be corrected at once as

specified and/or removed and made good.

Along forms, kerbs, walls or other places not accessible to the roller, the mixture shall be thoroughly compacted with mechanical

tampers or a plate compactor. Skin patching of an area without scarifying the surface to permit proper bonding of the added

material shall not be permitted.

Rolling should not be done when the subgrade is soft or yielding or when it causes a wave-like motion in the sub-base/base course

or subgrade. If irregularities develop during rolling which exceed 12 mm when tested with a 3 metre straight edge, the surface

should be loosened and premixed material added or removed as required before rolling again so as to achieve a uniform surface

conforming to the desired grade and crossfall. In no case should the use of unmixed material be permitted to make up the

depressions. Rolling shall be continued till the density achieved is at least 98 per cent of the maximum dry density for the material

as determined by the method outlined in IS : 2720 (Part-8).

After completion, the surface of any finished layer shall be well-closed, free from movement under compaction equipment or any

compaction planes, ridges, cracks and loose material. All loose, segregated or otherwise defective areas shall be made good to the

full thickness of the layer and recompacted.

Setting and drying:

Clause : 5 SCHEDULE OF MAINTENANCE

To keep paver blocks and footpaths durable, safe, and aesthetically pleasing, a structured maintenance schedule is essential. Pavers are

"interlocking" systems, meaning their strength relies on the sand in the joints; if the sand disappears, the blocks move and eventually

Below is a comprehensive maintenance and repair schedule categorized by frequency.

1. Common Defects & Repair Actions

When inspections reveal issues, use this guide to determine the repair method:

A. Sunken or Uneven Blocks (Settlement)

 Cause: Poor base compaction or water washing away the bedding sand.

 Repair: 1. Carefully lift the affected blocks using a flat-head screwdriver or paver extractor.

2. Add additional bedding sand to the base and compact it.

3. Re-install the blocks and sweep new sand into the joints.

B. Missing Joint Sand (The "Linchpin" of Pavers)

 Cause: Rain, wind, or aggressive power washing.

 Repair: Sweep Polymeric Sand into the joints. This sand contains a binder that hardens when misted with water, making it

resistant to washouts and weeds.

C. Cracked or Chipped Blocks

 Cause: Heavy vehicle impact or freeze-thaw cycles.

 Repair: Individual blocks should be replaced. This is why it is recommended to keep "attic stock" (extra blocks) from the

original installation to ensure a color match.

2. Checklist for Footpaths

 Contractor shall execute maintenance works as directed by the client and through self-inspection under the instruction of

Engineer-In-Charge.

 Surveying of footpaths and paver blocks shall be undertaken as and when required on the designated roads and chawls, as

instructed by Engineer-In-Charge.

 The inspection schedule shall be aligned with the following categories of complaints, with priorities determined by the Engineer-

o CCRS complaints

o Complaints from MLSs/ Councilors

o Complaints from Officials

 The specific roads and chawls shall be surveyed as per below schedule as specified.

o The contractor shall visit the ward office once a week to obtain details of the roads scheduled for inspection and

conduct a survey of footpaths and paver blocks, as directed by the Engineer-in-Charge (EIC)

 The Contractor shall adhere to the maintenance schedule outlined in the tender documents and comply with the prevailing AMC

circulars of SOM issued from time to time.
