IS Sieve Designation Percent by weight passing the IS Sieve

600 micron 8-22

Material finer than 425 micron shall have Plasticity Index (PI) not exceeding

The final gradation approved within these limits shall be graded from coarse to fine and shall not vary

from the low limit on one sieve to the high limit on the adjacent sieve or vice versa.

Construction Operations:-

Preparation of Base

Ahmedabad Municipal Corporation

The surface of the sub-grade/sub-base/base to receive the Wet mix macadam course shall be prepared

to the specified 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:

(i) Loading hoppers and suitable distribution mechanism

(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 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.

Ahmedabad Municipal Corporation

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

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.

Surface Finish and Quality Control of Work

Surface evenness:

The surface finish of construction shall conform to the requirements of Clause in Item No. 16&17&18.

Quality control:

Control on the quality of materials and works shall be exercised by the Engineer as per Table 19-3.

thickness of the layer shall be scarified over the affected area, reshaped with added premixed material

or removed and replaced with fresh premixed material as applicable and recompacted. The area

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

Ahmedabad Municipal Corporation

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

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 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 opinion of Engineer-in-charge are of

such an extent or character so as to affect 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.
