materials in adjoining shoulders along with that the wet mix
macadam layer and following the sequence of operations described
in Clause 407.4.1 of MORT & H.
5.2.3.3 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. For small quantity of wet mix
work, the Engineer may permit the mixing to be done in concrete
mixers.
Optimum moisture for mixing shall be determined in accordance
with IS:2720 (Part-8) after replacing the aggregate fraction retained
CIDCO OF MAHARASHTRA LIMITED. Sl.Pg.No.218 C.A.NO.11/CIDCO/EE(KLM-I)/2012-13
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.
5.2.3.4 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 motor grader or a paver finisher
or motor grader. For portions where mechanical means cannot be
used, manual means as approved by the Engineer shall be used.
The motor grade 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) Moving 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.
CIDCO OF MAHARASHTRA LIMITED. Sl.Pg.No.219 C.A.NO.11/CIDCO/EE(KLM-I)/2012-13
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 spots remedied by removing or adding
aggregate as may be required. The layer may be tested by depth
blocks during construction. No segregation of large and fine
particles should be allowed. The aggregates as spread should be of
uniform gradation with no pockets of fine/coarse materials.
5.2.3.5 Compaction :
After mix have 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 100mm, a smooth wheel roller of 80 to 100 kN weight
may be used. For a compacted single layer upto 200mm, the
compaction shall be done with the help of vibratory roller of
minimum static weight of 80 to 100 kN of equivalent capacity roller.
The speed of the roller shall not exceed 5 km./hr.
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
centre line of the road, uniformly overlapping each preceding track
by at least one third width until the entire surface has been rolled.
Alternate strips of the roller shall be terminated in stops at least 1 m.
away from any preceding stop.
CIDCO OF MAHARASHTRA LIMITED. Sl.Pg.No.220 C.A.NO.11/CIDCO/EE(KLM-I)/2012-13
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 the roller or from any other cause shall be corrected at once as
specified and/or removed the 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 sub-grade is soft or yielding or
when it causes a wave-like motion in the sub-base/base course or
sub-grade. If irregularities develop during rolling which exceed 12
mm when tested with a 3 metre straight edge, the surface should be
loosed 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 should the use of unmixed
material be permitted to make up the depressions.
Rolling should be continued till the density achieved is at least 98%
of the maximum dry density for the material as determined by the
method outlined in IS:2720 (Part 8).
CIDCO OF MAHARASHTRA LIMITED. Sl.Pg.No.221 C.A.NO.11/CIDCO/EE(KLM-I)/2012-13
After completion, the surface of any finished layer should 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

Low porosity 30 – 60 6 to 9 Medium porosity 70 – 140 9 to 12
High porosity 250 – 500 12 to 15
6.2.3 Choice of primer :
The primer shall be bitumen emulsion, complying with IS 8887 of a
type and grade as specified in the contract or as directed by the
Engineer. The use of medium curing cutback as per IS 217 shall be
restricted only for sites at sub-zero temperatures or for emergency
applications as directed by the Engineer.
6.3 WEATHER AND SEASONAL LIMITATIONS :
Bituminous primer shall not be applied to a wet surface or during dust
storm or when the weather is foggy, rainy or windy or when the
CIDCO OF MAHARASHTRA LIMITED. Sl.Pg.No.224 C.A.NO.11/CIDCO/EE(KLM-I)/2012-13
temperature in the shade is less than 100C. Surfaces which are to
receive emulsion primer should be damp, but no free or standing water
shall be present.
6.4 CONSTRUCTION :
6.4.1 Equipment :
The primer distributor shall be a self- propelled or towed bitumen
pressure sprayer equipped for spraying the material uniformly at
specified rates and temperatures. Hand spraying of small areas,
inaccessible to the distributor, or in narrow strips shall be sprayed
with a pressure hand sprayer, or as directed by the Engineer.
6.4.2 Preparation of road surface :
The surface to be primed shall be prepared in accordance with Clause
501.8 and 902 of MORT & H (Fourth Revision) as appropriate.
Immediately prior to applying the primer the surface shall be carefully
swept clean of dust and loose particles, care being taken not to disturb
the interlocked aggregate. This is best achieved when the surface layer
is slightly moist (lightly sprayed with water and the surface allowed do
dry) and the surface should be kept moist until the primer is applied.
6.4.3 Application of bituminous primer :
The viscosity and rate of application of the primer shall be as
specified in the contract or as determined by site trials carried out as
directed by the Engineer. Where a geosynthetic is proposed for use,
the requirements of Clauses 703.3.2 & 703.4 of MORT&H
specifications shall apply. The bituminous primer shall be sprayed
uniformly in accordance with Clause 501 of MORT & H
specifications. The method of application of the primer will depend
CIDCO OF MAHARASHTRA LIMITED. Sl.Pg.No.225 C.A.NO.11/CIDCO/EE(KLM-I)/2012-13
on the type of equipment to be used, size of nozzles, pressure at the
spray bar and speed of forward movement. The contractor shall
demonstrate at a spraying trial, that the equipment and method to be
used is capable of producing a uniform spray, within the tolerances
specified. The bitumen sprayer shall have a flow meter arrangement
(duly calibrated) for measurement / rate of spraying and
reconciliation of material.
6.4.4 Curing of primer and opening to traffic :
A primed surface shall be allowed to cure for at least 24 hours or
such other period as is found to be necessary to allow all the volatiles
to evaporate before any subsequent surface treatment or mix is laid.
Any unabsorbed prime shall first be blotted with an application of
sand, using the minimum quality possible. A primed surfaces shall
not be opened to traffic other than that necessary to lay the next
course. A very thin layer of clean san may be applied to the surface

3.0 SPECIFICATIONS FOR READY MIX CONCRETE
3.1 Batching of Concrete ingredients :
For all structural concreting, only Ready Mixed Concrete (RMC)
obtained from approved R.M.C. supplying agencies is mandatory.
The R.M.C. supplying agency will supply mix design details in
advance before start of delivery.
3.2 Transporting, placing, compacting, finishing and curing :
Transporting, placing, compacting, finishing and curing of concrete
shall be in accordance with IS:456-2000.
3.2.1 Transporting :
For all RMC concreting, the concrete after discharge from batching
plant will be loaded in transit mixers and kept continuously agitated
while mix is in transit. At destination the mix will be unloaded in to
the hoppers of concrete pump. For site made concrete suitable
prescribed methods shall be adopted.
3.2.2 Placing :
The concrete produced in RMC plant/batching plant, when
discharged from transit mixer in pump hopper shall be kept
continuously agitated and pumped to destination placing point. Site
made concrete shall be placed by approved method of placing. The
height of any single lift of concrete shall not exceed 1.5 m for walls.
Where the height of pour is more than 2.0 m, suitable arrangement in
CIDCO OF MAHARASHTRA LIMITED. Sl.Pg.No.278 C.A.NO.11/CIDCO/EE(KLM-I)/2012-13
formwork should be made so that the vertical drop of concrete is
restricted to less than 2.0 m. Any such arrangement should be
approved from the Engineer in advance before execution.
High velocity discharge of concrete causing segregation of mix shall
be avoided. The concrete shall be placed in the forms gently and not
dropped from the height exceeding 1.5 m. Each batch of concrete
will be placed in layer. Each layer of concrete shall be compacted
fully before the succeeding layer is placed and separate batches shall
be placed and fully compacted before the layer immediately below
has taken initial set. The layers should be sufficiently shallow, to
permit stitching of two layers together by vibration.
Concreting of any portion or section of the work shall be carried out
in one continuous operation and no interruption of concreting work
will be allowed without approval of the Engineer.
Plain concrete in foundations shall be placed, in direct contact, with
the bottom of excavation, the concrete being deposited in such a
manner, as not to get mixed with the earth. The concrete placed
below the ground level shall be protected from falling earth during
and after placing. Concrete placed in ground containing deleterious
substances, shall be kept free from contact, with such ground and
with water draining there from during placing and for a period of 7
days or otherwise instructed there after. Approved means shall be
taken to protect immature concrete from damage by debris, excessive
loading, abrasion, vibrations, deleterious ground water, mixing with
earth and other materials and other influences that may impair
strength and durability of concrete.
CIDCO OF MAHARASHTRA LIMITED. Sl.Pg.No.279 C.A.NO.11/CIDCO/EE(KLM-I)/2012-13
3.2.3 Compaction :
External, Internal (needle) and surface (screed board) vibrators shall
be used for compaction of concrete
a) External/internal needle vibrators shall be used for compaction of
concrete. For sections such as slabs, the concrete shall be
compacted by external, internal and surface type vibrators,
depending on the thickness of layer to be compacted. 25mm,
40mm and 60mm dia internal vibrators may be used. The
concrete shall be compacted by use of appropriate diameter
vibrator by holding the vibrator in position until :
i) Air bubbles cease to come to surface
ii) Resumption of steady frequency of vibrator after short
period of dropping the frequency, when the vibrator is first
inserted.
iii) The tone of the vibrator becomes uniform
iv) Flattened, glistening surface, with coarse aggregates
particles blended into it, appears on the surface.
After the compaction is completed, the vibrator should be
withdrawn slowly from concrete so that concrete can flow in
to the space previously occupied by the vibrator. To avoid
segregation during vibration, the vibrator shall not be
dragged through the concrete nor used to spread the
concrete. The vibrator shall be made to penetrate into layer
of fresh concrete below if any, for a depth about 150mm.
The vibrator shall be made to operate at regular pattern of
CIDCO OF MAHARASHTRA LIMITED. Sl.Pg.No.280 C.A.NO.11/CIDCO/EE(KLM-I)/2012-13
spacing. The effective radii of action will overlap,
approximately half a radius to ensure complete compaction.
v) To secure even and dense surfaces free from aggregate
pockets, vibration shall be supplemented by tamping or
rodding by hand in the corners of forms and along the form
surfaces while the concrete is plastic.
vi) A sufficient number of spare vibrators shall be kept readily
accessible to the place of deposition of concrete to assure
adequate vibration in case of breakdown of those in use.
vii) Plain concrete also shall be vibrated whenever and wherever
directed by Engineer to achieve full compaction, using
needle and screed vibrators as necessary.
3.2.4 Curing :
Curing shall be started at the earliest by spreading wet jute cloth
(hessian) and cover top with impervious sheet and subsequently
cured with spraying water. In inaccessible area to start with, curing
be started by spraying curing compound before starting membrane
curing.
3.3 Placing temperatures :
During extreme hot weather, the concreting shall be done as per
procedures set out in IS:7861, Parts I & II.
The placing temperature of concrete shall be as low as possible in
warm weather and care shall be taken to protect freshly placed
concrete form overheating by sunlight in the first few hours of its
laying.
CIDCO OF MAHARASHTRA LIMITED. Sl.Pg.No.281 C.A.NO.11/CIDCO/EE(KLM-I)/2012-13
3.4 Construction joints :
Construction joints in all concrete work shall be made as directed by
the Engineer. Where vertical joints are required, these shall be
shuttered as directed and not allowed to take the natural slope of the
concrete.
Before fresh concrete is placed against a vertical joint, the old
concrete shall be chipped/sand blasted, cleaned and moistened before
placing the concrete. All standing water should be removed and
dried with compressed air. Neat cement slurry shall be applied on
the chipped/sand blasted surface and mortar of the same water
cement ratio as the concrete and 10mm thick applied.
3.5 Exposed Faces, Holes and Fixtures :
On no account shall concrete surfaces be patched or covered up or
damaged concrete rectified or replaced until the Engineer or his
representative has inspected the works and issued written
instructions for rectification. Failure to observe this procedure will
render that portion of the works liable to rejection; in which case it
will be treated as a work which has failed to meet specified strength
requirements.
3.6 Cracks :
3.6.1 If cracks develop in concrete construction which in the opinion of the
Engineer may be detrimental to the strength of the construction, the
contractor at his own expense shall test the slab or other
construction. If under such test loads the cracks develop further, the
Contractor shall dismantle the construction, carry away the debris,

without any extra payment.
3.6.2 If any cracks develop in the concrete construction, which in the
opinion of the Engineer, are not detrimental to the strength of the
construction, the contractor at his own expense shall grout the cracks
with polymer cement grout of approved quality at his own expense
and risk and shall make good to the satisfaction of the Engineer the
surface finish which in the opinion of the Engineer has suffered
damage either in appearance or stability owing to such cracks. The
Engineer’s decision as to the extent of the liability of the Contractor
in the above matter shall be final and binding.
3.7 Finishes :
Unless otherwise instructed the face of exposed concrete placed
against formwork shall be rubbed down immediately on removal of
the formwork to remove irregularities. The face of concrete for
which formwork is not provided other than slabs shall be smoothed
with a float to give a finish equal to that of the rubbed down face,
where formwork is provided. The top face of a slab which is not
intended to be covered with other materials shall be leveled and
floated to a smooth finish at the levels or falls shown on the drawings
or as directed. The floating shall be done so as not to bring as
excess of mortar to the surface of the concrete. The top face of a
slab intended to be surfaced with other materials shall be left with a
spaded finish. Face of concrete intended to be plastered shall be
roughened by approved means to form a key.

3.11.3 Water, Admixtures and slump :
The amount of water required for proper concrete consistency shall
take into account the rate of mixing, length of haul, time of
unloading and ambient temperature conditions.
Additions of water to compensate for slump loss should not be
resorted to nor should the design maximum water-cement ratio be
exceeded. Additional dose of retarder/plasticizer/superplasticizer
shall be used with prior approval of Engineer to compensate the loss
of setting time and slump at contractor’s cost. Retempering water
shall not be allowed to be added to mixed batches to obtain desired
slump.
3.11.4 Transportation :
The method of transportation used should efficiently deliver the
concrete to the point of placement without significantly altering its
desired properties with regard to water-cement ratio, slump, and
homogeneity.
The revolving-drum truck bodies of approved make shall be used for
transporting the concrete. The number of revolutions at mixing
speed, during transportation, and prior to discharge shall be specified
and agreed upon. Reliable counters shall be used on revolving-drum
truck units. Standard mixer uniformity tests, conforming to ASTM
standards C 94-69 “Standard Specifications for Ready Mix
Concrete”, shall be carried out if desired by Engineer to determine
whether mixing is being accomplished satisfactorily.

3.11.5 Field control :
Sampling at both truck discharge and point of final placement shall
be employed to determine if any changes in the slump and other
significant mix characteristics occur. However, for determining
strength of concrete, cubes shall be taken from the placement end of
line. The RMC supplier should nominate a technically qualified
representative at site for sampling, testing and placing of concrete.
3.12 Planning :
Proper planning of concrete supply, line layout, placing sequence
etc. shall be made. The concrete production, transportation and
placing shall be planned in such a manner that duration between
addition of water during mixing and placing of concrete in desired
location is well within time limits prescribed by the RMC
manufacturer, however, this is subjected to fulfillment of slump and
other properties of concrete as specified in tender. On failure to
adherer to the time schedule by the supplier the Engineer may reject
the concrete.
The placing rate should be estimated so that concrete can be ordered
at an appropriate delivery rate.
