grade and camber and cleaned of dust, dirt and other extraneous material. Any ruts or soft yielding places shall be

corrected in an approved manner and rolled until firm surface is obtained.

Where the Wet mix macadam is to be laid on an existing metalled road, damaged area including depressions and

potholes shall be 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.

Quantity of water should not vary from OMC determined as per IS : 2720 (part VIII) by more than agreed limit. The

mixed material 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. The motor grader shall be capable of spreading the material uniformly all over the surface.

Its blade shall have hydraulic control suitable for initial adjustments and maintaining the same so as to achieve the

specified slope and grade.

The paver finisher shall be self-propelled, having the following features:

 Loading hoppers and suitable distribution mechanism

 The screed shall have tamping and vibrating arrangement for initial compaction to the layer as it is spread

without rutting or otherwise marring the surface profile.

 The paver shall be equipped with necessary control mechanism so as to ensure that the finished surface is free

from surface blemishes.

The surface of the aggregate shall be carefully checked with templates and all high or low sports remedied by

removing or adding 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

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-

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:

After final compaction of wet mix macadam course, the road shall be allowed to dry for 24 hours.

Opening to Traffic

Preferably no vehicular traffic of any kind should be allowed on the finished wet mix macadam surface till it has dried

and the wearing course laid.

determined by Engineer. Concrete shall be protected against damage until final acceptance.

Curing and protection shall start immediately after the compaction of concrete to protect it from:

(a) Premature drying out, particularly by solar radiation and wind;

(b) Leaching out by rain and flowing water;

(c) Rapid cooling during the first few days after placing;

(d) High internal thermal gradients;

(e) Low temperature of frost;

(f) Vibration and impact which may disrupt the concrete and interfere with its bond to the reinforcement.All concrete,

unless directed otherwise by Engineer, shall be cured by use of continuous sprays or pounded water or continuously

saturated coverings of sacking, canvas, hessian or other absorbent material for the period of complete hydration with

a minimum of 7 days. The quality of curing water shall be the same as that used for mixing.Where a curing membrane

is directed to be used by the Engineer, the same shall be of a non-wax base and shall not impair the concrete finish in

any manner. The curing compound to be used shall be got approved from the Engineer before use and shall be applied

with spraying equipment capable of a smooth, even textured coat. Curing may also be done by covering the surface

with an impermeable material such as polyethylene, which shall be well sealed and fastened. Extra precautions shall

by the Engineer. All such rectification of the Client / Engineer at no extra cost to the Client.

TESTING CONCRETE STRUCTURE FOR LEAKAGE

Hydro-static test for water tightness shall be done at full storage by Engineer, as described below:

In case of structures whose external faces are exposed, such as elevated tanks, the requirements of the test shall be

deemed to be satisfied if the external faces show no sign of leakage or sweating and remain completely dry during the

period of observation of seven days after allowing a seven day period for absorption after filling with water.In case of

structures whose external faces are submerged and are not accessible for inspection, such as underground tanks, the

structures shall be filled with water and after the expiry of seven days after filling,the level of the surface of the water

shall be recorded. The level of water shall be recorded again at subsequent intervals of 24 hrs, over a period of seven

days. Backfilling shall be withheld till the tanks are tested. The total drop in surface level over a period for seven day

shall be taken as an indication of the water tightness of the structure. The Engineer shall decide on the actual

permissible nature of this drop in the surface level, taking into account weather the structures are open or closed and

the corresponding effect it has on evaporation losses. Unless specified otherwise, a structure whose top is covered

shall be deemed to be water tight if the total drop in the surface level over a period of seven days does not exceed

Each compartment/segment of the structure shall be tested individually and then all together.For structures such as

pipes, tunnels etc. the hydro-static test shall be carried out by filling with water, after curing as specified, and

subjecting to the specified test pressure for specified period. If during this period the loss of water does not exceed the

equivalent of the specified rate, the structure shall be considered to have successfully passed the test.

If Engineer feels that the materials i.e. .cement, sand coarse aggregates, reinforcement and water are not in

accordance with the specifications or if specified concrete strengths are not obtained, he may order tests to be carried

out on these materials in laboratory, to be approved by the Engineer, as per relevant IS Codes. Client shall pay only for

the testing of material supplied by the Client, otherwise Contractor shall have to pay for the tests. Transporting of all

material to the laboratory shall however be done by the Contractor at no extra cost to client. In the even of any work

being suspected of faulty material or workmanship requiring its removal or if the works cubes do not give the

stipulated strengths, Engineer reserves the right to order the Contractor to take out cores and conduct tests on them

or do ultrasonic testing or load testing of structure, etc. All these tests shall be carried out by Contractor at no extra

cost to the Client. Alternatively Engineer also reserves the right to ask the Contractor to dismantle and re-do such

unacceptable work at the cost of Contractor. If the quoted unit rates/prices of concrete shall be deemed to provide for

all tests mentioned above.

All materials, workmanship and finished construction shall be subject to continuous inspection and approval of

Engineer. Materials rejected by Engineer shall be expressly removed from site and shall be replaced by Contractor

surfaces have uniform colour.

For all kind of exposed concrete work only one brand (to be approved by the Engineer-in charge)of cement shall be

Removal of Moulds:

Specific time shall be identified for removal of moulds, such that the concrete of the Precast blocks shall gain

strength to withstand the stresses generated due to self weight and handling to drying yards without any

deformation to shape/ dimensions/ edges.

Drying Period: Sufficient time shall be given to the block after it is removed from the mould so that it can gain

strength and dry in shade to prevent any cracks due to shrinkage. This shall be done in drying yards.

Curing of block shall be done only in curing pond and curing shall be done for minimum 14 days.

Drying period after removing from pond & before delivery to site:

Water should be drained of from the block before it is actually sent to the site. Time should be provided for

proper draining of water which may be present in the block kept for curing in the pond.

Precaution shall be taken while transporting of the blocks to site.

The blocks should be loaded and unloaded with due care so as to avoid generation of stresses leading to breaking of

block. Care should be taken to prevent the block from breaking during transporting.

minimum seven days.

Sampling and testing of concrete:

Samples from fresh concrete shall be taken as per IS : 1199-1959 and cubes shall be made, cured and tested at

7 days or 28 days as per requirements in accordance with IS : 516-1959. A random sampling procedure shall be

adopted to ensure that each concrete batch shall have a reasonable chance of being tested i.e. the sampling should

be spread over the entire period of concreting and cover all mixing units.

At least 1 sample shall be taken from each shift. Ten test specimens shall be made from each sample, 5 for

testing at 7 days and the remaining 5 at 28 days. The samples of concrete shall be taken on each day of the

concreting as per above frequency. The number of specimens may be suitably increased as deemed necessary by the

Engineer-in-charge when procedure of tests given above reveals a poor quality of concrete and in other special cases.

The average strength of the group of cubes cast for each day shall not be less than the specified cube strength of

Kg/cm2. at 28 days. 20% of the cubes cast for each day may have value less than the specified strength provided the

lowest value is not less than 85% of the specified strength. If the concrete made in accordance with the proportions

given for a particular grade, does not yield the specified strength, such concrete shall be classified as belonging to the

appropriate lower grade. Concrete made in accordance with the proportions given for a particular grade shall not,

however, be placed in a higher grade on the ground that the test strength are higher than the minimum specified. If

rock pockets/honeycombs in the opinion of Engineer-in-charge are of such an extent or character so as to effect the

strength of the structure, materially or to endanger the life of the steel reinforcement, he may declare the concrete

defective and require the removal and replacement of the portion of the structure affected.
