Construction OperationsPreparation of Base

Clause 404.3.1 shall apply.

Provision of Lateral Confinement of Aggregates

While constructing wet mix macadam, arrangement shall be made for the lateral confinement of wet

mix. This shall be done by laying materials in adjoining shoulders along with that of wet mix macadam

layer and following the sequence of operations described in Clause 404.3.3.

Preparation of Mix

Wet Mix Macadam shall 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. The plant shall have following features:

i) For feeding aggregates- three/ four bin feeders with variable speed motor

ii) Vibrating screen for removal of oversize aggregates

iii) Conveyor Belt

iv) Controlled system for addition of water

v) Forced/positive mixing arrangement like pug-mill or pan type mixer

vi) Centralized control panel for sequential operation of various devices and precise process control

vii) Safety devices

Optimum moisture for mixing shall be determined in accordance with IS:2720 (Part-8) after replacing

the aggregate fraction retained on 22.4 mm sieve with material of 4.75 mm to 22.4 mm size. While

adding water, due allowance should be made for evaporation losses. However, at the time of

compaction, water in the wet mix should not vary from the optimum value by more than agreed limits.

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 sub-

grade/sub-base/base in required quantities. In no case shall 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 by a paver finisher. The paver finisher shall be self-propelled of adequate

capacity with following features:

i) Loading hoppers and suitable distribution system, so as to provide a smooth uninterrupted

material flow for different layer thicknesses from the tipper to the screed.

ii) Hydraulically operated telescopic screed for paving width up to to 8.5 mand fixed screed beyond

this. The screed shall have tamping and vibrating arrangement for initial compaction of the

layer.Automatic levelling control system with electronic sensing device to maintain mat thickness and

cross slope of mat during laying procedure.

In exceptional cases where it is not possible for the paver to be utilized, mechanical means like motor

spreading the material uniformly all over the surface.

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

remedied by removing or adding aggregate as may be required. The layer may be tested by depth

blocks during construction. No segregation of larger and fine particles should be allowed. The

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

The Engineer may permit manual mixing and /or laying of wet mix macadam where small quantity of

wet mix macadam is to be executed. Manual mixing/laying in inaccessible/ remote locations and in

situations where use of machinery is not feasible can also be permitted. Where manual mixing/laying is

intended tobe used, the same shall be done with the approval of the Engineer.

After the mix has been laid to the required thickness, grade and cross fall/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, a smooth wheel roller of 80 to 100kN weight may be used. For a compacted

single layer up to 200 mm, the compaction shall be done with the help of vibratory roller of minimum

static weight of 80 to 100 kN with an arrangement for adjusting the frequency and amplitude. An

appropriate frequency and amplitude may be selected. The speed of the roller shall not exceed 5 km/h.

In portions having unidirectional cross fall/super elevation, rolling shall commence from the lower edge

and progress gradually towards the upper edge. Thereafter, roller should progress parallel to the center

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

scarifyingthe surface to permit proper bonding of the added material shall not be permitted.

Rolling should not be done when the sub-grade is soft or yielding or when it causes a wavelike motion in

the sub-base/base course or sub-grade. If irregularities develop during rolling which exceed 12 mm

when tested with a 3 m 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 cross fall. In no case shall the use of unmixed material be permitted to make up the

Rolling shall be continued till the density achieved is at least 98 percent 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 re

material / items in General technical specification for building work of R&B Department of Gujarat.

Water shall conform to M-1

Graded stone aggregate 20 mm. nominal size to M-10

Contractor shall have to manufacture the blocks as per the dimensions given in the drawing. Specific

machineries shall be used to manufacture the precast blocks. These machineries should be compatible

to produce blocks of required strength and dimensions. The machine shall contain hydraulic Press or

advanced equipment to generate required compaction & Grade and finish. Moulds/ Steel Plates/ Dies of

the machine shall be dimensionally checked & to be got approved before commencing the production.

Contractor shall prepare proper Drying Yard for keeping the blocks before curing. The drying yard shall

be levelled and covered so that no shrinkage cracks are formed. Contractor shall prepare adequate size

curing pond to cure the blocks for not less than 21 Days. No other means of curing shall be allowed.

The technical specification of concrete shall confirm to IS 456-2000. The concrete mix is not required to

be designed and only nominal mix as per IS: 456-2000 shall be followed. The proportion of the concrete

mix shall be 1:1.5:3 (1 cement: 1.5 coarse sand: 3 graded stone aggregate 20 mm. nominal size) by

volume. Concrete work shall have fairly exposed concrete surface or as specified in the item. The

designation ordinary M-10, M-15, M-20, M-25 specified as per I.S. corresponds approximately to 1:3:6,

1:2:4, 1:1.5:3 and 1:1:2 nominal mix of ordinary concrete, by volume respectively. The ingredients

required for ordinary concrete containing one bag of cement of 50 Kg. by weight (0.0342 m3.) for

different proportions of mix shall be as per IS 456-2000. The proportion of the aggregate for the kerb

stone shall be modified as per the approval of the engineer-in-charge. The water cement ratios shall not

be more than those specified as per IS. The cement of the mix shall be increased, if the quantity of

water in a mix has to be increased to overcome the difficulties of placement and compaction so that the

water cement ratio specified in the table is not exceeded. The maximum size of coarse aggregate shall

be as large as possible within the limits specified but in no case greater than 1/4th of the minimum

thickness of the member, provided that the concrete can be placed without difficulty so as to surround

all reinforcement thoroughly and to fill the corners of the form. For reinforced concrete work, coarse

aggregates having a nominal size of 20 mm. are generally considered satisfactory. Admixture shall be

used in concrete only with approval of the Engineer-in-charge based upon the evidence that with the

passage of time, neither the compressive strength of concrete is reduced nor are other requisite

qualities of concrete impaired by the use of such admixtures.

Proportioning shall be done by volume, except cement which shall be measured in terms of bags of

kg weight. The volume of one such bag can be taken as 0.0342 m3. Boxes of suitable sizes shall be used

for measuring sand and aggregate. The size of the boxes (internal) shall be 30cm. x 30 cm. and 38 cm.

deep. While measuring the aggregate and sand, the box shall be filled without shaking ramming or

hammering. The proportioning of sand shall be on the basis of its dry volume and in case of damp sand;

allowances for bulk age shall be made.

For all work, concrete shall be mixed in a mechanical mixer which along with other accessories shall be

kept in first class working condition and maintained throughout the construction. Measured quantity of

aggregate, sand, and cement required for each batch shall be poured into the drum of the mechanical

mixer while it is continuously running. After about half a minute of dry-mixing, measured quantity of

water required for each batch of concrete mix shall be added gradually and mixing continued for

another one and a half minute. Mixing shall be continued till materials are uniformly distributed and

uniform colour of the entire mass is obtained and each individual particle of the coarse aggregate shows

complete coating of mortar containing its proportionate amount of cement. In no case shall the mixing

be done for less than 2 minutes after all ingredients have been put into the mixer. Mixers which have

been out of use for more than 30 minutes shall be thoroughly cleaned before putting in a new batch.

Unless otherwise agreed to by the Engineer-in-charge, the first batch of concrete from the mixture shall

contain only 2/3rds of normal quantity of coarse aggregate. Mixing plant shall be thoroughly cleaned

before changing from one type of cement to another.

The degree of consistency which shall depend upon the nature of the work and methods of vibration of

concrete shall be determined by regular slump tests in accordance with IS: 1199-1959. The slump of

mm. to 25 mm. shall be adopted when vibrators are used.

All Moulds shall be cleaned and made free from standing water, dust, snow, or ice immediately before

placing of concrete.

Formwork/Metal Mould for exposed concrete surface (If indicated):

All the moulds shall be checked for exact dimensions of the precast blocks. All the edges of the precast

blocks shall confirm the profile of the final drawing & edges/ curvatures of the moulds shall be checked

accordingly. Moulds shall be regularly checked for correctness of dimensions of Blocks, twists, bends

due to handling, etc. Before starting every days work.

Care shall be taken to set all form work/Mould in perfect line, level (or in required camber or slope as

specified) and plumb. Form work/Mould propping shall be strong, rigid, and sturdy. The form

work/Mould shall be as per pattern & design shown in drawings. Form work/Mould shall be done

accurately and precisely so as to achieve neat, clean and smooth concrete surface, in line, level and

plumb. Clinks, twists, offsets, warps, riveting etc. in plates or forms shall not be allowed. Before placing

concrete, forms shall be thoroughly cleaned off of all rust, dust, and loose materials. Colourless oil or

grease of approved quality shall be applied before placing steel. Also the form work material will be of

wood/plywood/steel or any sort of such material, as approved by the Engineer-in-Charge and/or his

authorized representative; so that all exposed concrete 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 used.

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.

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.

The pits of the size 150mm in width and required depth shall first be excavated, true to line and level.

The relevant specifications of item A- 1 shall be followed for excavation work. The pits shall be filled

with a layer of 50mm. thick sand bedding. The curbs then shall be placed in position of which 50mm.

shall be below road. Care should be taken to maintain proper line and level. The joints between the

kerbs shall be pointed with C.M. 1:2 and cured for 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,

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.
