prepared to the specified grade and camber and cleaned of dust, dirt and other extraneous material.

Ahmedabad Municipal Corporation

Any ruts or soft yielding places shall be corrected in an approved manner and rolled until firm surface

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

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:

(ii) 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.

(iii) 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

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

Ahmedabad Municipal Corporation

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 :

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

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.

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 200 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
