The limits of embankment/sub-grade shall be marked by fixing batter pegs on both sides at regular intervals as guides
before commencing the earthwork. The embankment/sub-grade shall be built sufficiently wider than the design
dimension so that surplus material may be trimmed, ensuring that the remaining material is to the desired density and in
position specified and conforms to the specified side slopes.
If the foundation of the embankment is in an area with stagnant water, and in the opinion of the Engineer it is feasible to
remove it, the same shall be removed by bailing out or pumping, as directed by the Engineer and the area of the
embankment foundation shall be kept dry. Care shall be taken to discharge the drained water so as not to cause damage
to the works, crops or any other property. Due to any negligence on the part of the Contractor, if any such damage is
caused, it shall be the sole responsibility of the Contractor to repair/restore it to original condition or compensate for the
damage at his own cost.
Stripping and Storing Topsoil
When so directed by the Engineer, the topsoil from all areas of cutting and from all areas to be covered by embankment
foundation shall be stripped to specified depths not exceeding 150 mm and stored in stockpiles of height not exceeding
m for covering embankment slopes, cut slopes and other disturbed areas where re-vegetation is desired. Topsoil shall not
be unnecessarily subjected to traffic either before stripping or when in a stockpile. Stockpiles shall not be surcharged or
otherwise loaded and multiple handling shall be kept to a minimum.
Compacting Ground Supporting Embankment/Sub-Grade
Where necessary, the original ground shall be levelled to facilitate placement of first layer of embankment, scarified,
mixed with water and then compacted by rolling in so as to achieve minimum dry density as given in Table 3-2.
In case where the difference between the sub-grade level (top of the sub-grade on which pavement rests) and ground
level is less than 0.5 m and the ground does not have 97 percent relative compaction with respect to the dry density (as
given in Table 3-2), the ground shall be loosened upto a level 0.5 m below the sub-grade level, watered and compacted in
layers to achieve dry density not less than 97 percent relative compaction as given in Table 3-2.
Where so directed by the Engineer, any unsuitable material occurring in the embankment foundation (500 mm portion
just below the sub-grade) shall be removed, suitably disposed and replaced by approved materials laid in layers to the
required degree of compaction.
Any foundation treatment specified for embankments especially high embankments, resting on suspect foundations as
revealed by borehole logs shall be carried out in a manner and to the depth as desired by the Engineer. Where the ground
on which an embankment is to be built has any of such material types (a) to (f) in Morth Clause 305.2.1.1 at least 500 mm
of such material must be removed and replaced by acceptable fill material before embankment construction commences.

The embankment and sub-grade material shall be spread in layers of uniform thickness in the entire width with a motor
grader. The compacted thickness of each layer shall not be more than 250 mm when vibratory roller/vibratory soil
compactor is used and not more than 200 mm when 80-100 kN static roller is used. The motor grader blade shall have
hydraulic control suitable for initial adjustment and maintain the same so as to achieve the specific slope and grade.
Successive layers shall not be placed until the layer under construction has been thoroughly compacted to the specified
requirements as in Table 3-2 and got approved by the Engineer. Each compacted layer shall be finished parallel to the
final cross-section of the embankment.
Moisture content of the material shall be checked at the site of placement prior to commencement of compaction; if
found to be out of agreed limits, the same shall be made good. Where water is required to be added in such
constructions, water shall be sprinkled from a water tanker fitted with sprinkler capable of applying water uniformly with
a controllable rate of flow to variable widths of surface but without any flooding. The water shall be added uniformly and
thoroughly mixed in soil by blading, using disc harrow until a uniform moisture content is obtained throughout the depth
Ahmedabad Municipal Corporation
If the material delivered to the roadbed is too wet, it shall be dried, by aeration and exposure to the sun, till the moisture
content is acceptable for compaction. Should circumstances arise, where owing to wet weather, the moisture content
cannot be reduced to the required amount by the above procedure, compaction work shall be suspended.
Moisture content of each layer of soil shall be checked in accordance with IS:2720 (Part 2), and unless otherwise
mentioned, shall be so adjusted, making due allowance for evaporation losses, that at the time of compaction it is in the
range of 1 percent above to 2 percent below the optimum moisture content determined in accordance with IS:2720 (Part
8) as the case may be. Expansive clays shall, however, be compacted at moisture content corresponding to the specified
dry density, but on the wet side of the optimum moisture content obtained from the laboratory compaction curve.
After adding the required amount of water, the soil shall be processed by means of graders, harrows, rotary mixers or as
otherwise approved by the Engineer until the layer is uniformly wet.

Embankments and unsupported fills shall not be constructed with steeper side slopes or to greater widths than those
shown in the drawings, except to permit adequate compaction at the edges before trimming back, or to obtain the final
profile following any settlement of the fill and the underlying material,
Whenever fill is to be deposited against the face of a natural slope, or sloping earthworks face including embankments,
cuttings, other fills and excavations steeper than 1 vertical to 4 horizontal, such faces shall be benched as per Morth
Clause 305.4.1 immediately before placing the subsequent fill.
All permanent faces of side slopes of embankments and other areas of fill shall, subsequent to any trimming operations,
be reworked and sealed to the satisfaction of the Engineer by tracking a tracked vehicle, considered suitable by the
Engineer, on the slope or any other method approved by the Engineer.
Only the compaction equipment approved by the Engineer shall be employed to compact the different material types
encountered during construction. Static three-wheeled roller, self propelled single drum vibratory roller, tandem
vibratory roller, pneumatic tyre roller, pad foot
roller, etc., of suitable size and capacity as approved by the Engineer shall be used for the different types and grades of
materials required to be compacted either individually or in suitable combinations.
The compaction shall be done with the help of self-propelled single drum vibratory roller or pad foot vibratory roller of
to 100 kN static weight or heavy pneumatic tyre roller of adequate capacity capable of achieving the required
compaction. The Contractor shall demonstrate the efficacy of the equipment he intends to use by carrying out
compaction trials. The procedure to be adopted for the site trials shall be submitted to the Engineer for approval.
Earthmoving plant shall not be accepted as compaction equipment nor shall the use of a lighter category of plant to
provide any preliminary compaction to assist the use of heavier plant be taken into account.
Each layer of the material shall be thoroughly compacted to the densities specified in Table 3-2. Subsequent layers shall
be placed only after the finished layer has been tested and accepted by the Engineer. The Engineer may permit
measurement of field dry density by a nuclear moisture/density gauge used in accordance with agreed procedure and
provided the gauge is calibrated to give results identical to that obtained from tests in accordance with IS:2720 (Part 28).
A record of the same shall be maintained by the Contractor.
When density measurements reveal any soft areas in the embankment/sub-grade/earthen shoulders, further compaction
shall be carried out as directed by the Engineer. If inspite of that the specified compaction is not achieved, the material in
the soft areas shall be removed and replaced by approved material, compacted using appropriate mechanical means such
Ahmedabad Municipal Corporation
as light weight vibratory roller, double drum walk behind roller, vibratory plate compactor, trench compactor or vibratory
tamper to the density requirements and satisfaction of the Engineer.
The surface of the embankment/sub-grade at all times during construction shall be maintained at such a crossfall (not
flatter than that required for effective drainage of an earthen surface) as will shed water and prevent ponding.
Repairing of Damages Caused by Rain/Spillage of Water
The soil in the affected portion shall be removed in such areas as directed by the Engineer before next layer is laid and
refilled in layers and compacted using appropriate mechanical means such as small vibratory roller, plate compactor or
power rammer to achieve the required. If the cut is not sufficiently wide for use of required mechanical means for
compaction, the same shall be widened suitably to permit their use for proper compaction. Tests shall be carried out as
directed by the Engineer to ascertain the density requirements of the repaired area. The work of repairing the damages
including widening of the cut, if any, shall be carried out by the Contractor at his own cost, including the arranging of
machinery/equipment for the purpose.
Finishing Operations
Finishing operations shall include the work of shaping and dressing the shoulders/verge/ roadbed and side slopes to
conform to the alignment, levels, cross-sections and dimensions shown on the drawings or as directed by the Engineer
subject to the surface tolerance described in Clause 902. Both the upper and lower ends of the side slopes shall be
rounded off to improve appearance and to merge the embankment with the adjacent terrain.
The topsoil, removed and conserved earlier shall be spread over the fill slopes as per directions of the Engineer to
facilitate the growth of vegetation. Slopes shall be roughened and moistened slightly prior to the application of the
topsoil in order to provide satisfactory bond. The depth of the topsoil shall be sufficient to sustain plant growth, the usual
thickness being from 75 mm to 150 mm.
When earthwork operations have been substantially completed, the road area shall be cleared of all debris, and ugly scars
in the construction area responsible for objectionable appearance eliminated.
Construction of Embankment and Sub-grade under Special Conditions
Earthwork for Widening Existing Road Embankment
When an existing embankment and/or sub-grade is to be widened and its slopes are steeper than 1 vertical on
horizontal, continuous horizontal benches, each at least 300 mm wide, shall be cut into the old slope for ensuring
adequate bond with the fresh embankment/subgrade material to be added. The material obtained from cutting of
benches could be utilized in the widening of the embankment/subgrade. However, when the existing slope against which
the fresh material is to be placed is flatter than 1 vertical on 4 horizontal, the slope surface may only be ploughed or
scarified instead of resorting to benching.
Where the width of the widened portions is insufficient to permit the use of conventional rollers, compaction shall be
carried out with the help of light weight vibratory roller, double drum walk behind roller, vibratory plate compactor or
vibratory tamper or any other appropriate equipment approved by the Engineer. End dumping of material from trucks for
widening operations shsll be avoided except in difficult circumstances when the extra width is too narrow to permit the
movement of any other types of hauling equipment.
Earthwork for Embankment and Sub-Grade to be Placed Against Sloping Ground
Where an embankment/subgrade is to be placed against sloping ground, the latter shall be appropriately benched or
ploughed/scarified before placing the embankment/sub-grade material. Extra earthwork involved in benching or due to
ploughing/ scarifying etc. shall be considered incidental to the work.
For wet conditions, benches with slightly inward fall and subsoil drains at the lowest point shall be provided as per the
drawings, before the fill is placed against sloping ground.
Earthwork over Existing Road Surface
Where the embankment is to be placed over an existing road surface, the work shall be carried out as indicated below:
Ahmedabad Municipal Corporation
i) If the existing road surface is of granular type and lies within 1 m of the new formation levels, it shall be scarified to a
depth of 50 mm or as directed so as to provide ample bond between the old and new material ensuring that at least
mm portion below the top of new sub-grade level is compacted to the desired density; ii) If the existing road surface is of
bituminous type or cement concrete and lies within 1 m of the new formation level, the bituminous or cement concrete
layer shall be removed completely; iii) If the level difference between the existing road surface and the new formation
level is more than 1 m, the existing surface shall be roughened after ensuring that the minimum thickness of 500 mm of
subgrade is available.
Embankment and Sub-Grade Around Structures
To avoid interference with the construction of abutments, wing walls or return walls of culvert/bridge structures, the
Contractor shall, at points, to be determined by the Engineer suspend work on embankment forming approaches to such
structures, until such time as the construction of the latter is sufficiently advanced to permit the completion of
approaches without the risk of damage to the structure.
Unless directed otherwise, the filling around culverts, bridges and other structures upto a distance of twice the height of
the road from the back of the abutment shall be carried out independent of the work on the main embankment. The fill
material shall not be placed against any abutment or wing wall, unless permission has been given by the Engineer but in
any case not until the concrete or masonry has been in position for 14 days. The embankment and sub-grade shall be
brought up simultaneously in equal layers on each side of the structure to avoid displacement and unequal pressure. The
sequence of work in this regard shall be got approved from the Engineer.
The material used for backfill shall not be an organic soil or highly plastic clay having plasticity index and liquid limit more
than 20 and 40 respectively when tested according to IS:2720 (Part 5). Filling behind abutments and wing walls for all
structures shall conform to the general guidelines given in IRC:78. The fill material shall be deposited in horizontal layers
in loose thickness and compacted thoroughly to the requirements of Table 3-2.
Where the provision of any filter medium is specified behind the abutment, the same shall be laid in layers
simultaneously with the laying of fill material.
Where it may be impracticable to use conventional rollers, the compaction shall be carried out by appropriate mechanical
means such as small vibratory roller, plate compactor or power rammer. Care shall be taken to see that the compaction
equipment does not hit or come too close to any structural member so as to cause any damage to them or excessive
pressure against the structure.
Construction of Embankment over Ground Incapable of Supporting Construction Equipment
Where embankment is to be constructed across ground which will not support the weight of repeated heavy loads of
construction equipment, the first layer of the fill may be constructed by placing successive loads of material in a uniformly
distributed layer of a minimum thickness required to support the construction equipment as permitted by the Engineer.
The Contractor, if so desired by him, may also use suitable geosynthetic material to increase the bearing capacity of the
foundation. This exception to normal procedure will not be permitted where, in the opinion of the Engineer, the
embankments could be constructed in the approved manner over such ground by the use of lighter or modified
equipment after proper ditching and drainage have been provided. Where this exception is permitted, the selection of
the material and the construction procedure to obtain an acceptable layer shall be the responsibility of the Contractor.
The cost of providing suitable traffic conditions for construction equipment over any area of the Contract will be the
responsibility of the Contractor and no extra payment will be made to him. The remainder of the embankment shall be
constructed as specified in tender document.
Embankment Construction under Water and Waterlogged Areas
Embankment Construction under Water
Where filling or backfilling is to be placed under water, only acceptable granular material or rock shall be used unless
otherwise approved by the Engineer. Acceptable granular material shall be of GW, SW, GP, SP as per IS:1498 and consist
of graded, hard durable particles with maximum particle size not exceeding 75 mm. The material should be non-plastic
having uniformity coefficient of not less than 10. The material placed in open water shall be deposited by end tipping
without compaction.
Embankment Construction in Waterlogged and Marshy Areas
The work shall be done as per instruction of Engineer-in-Charge and/or his authorized representative.
Ahmedabad Municipal Corporation
Earthwork for High Embankment
The material for high embankment construction shall conform to Clause in tender document. In the case of high
embankments (more than 6 m), the Contractor shall normally use fly ash in conformity or the material from the approved
Where provided, stage construction of embankment and controlled rates of filling shall be carried out in accordance with
the Contract including installation of instruments and its monitoring.
Where required, the Contractor shall surcharge embankments or other areas of fill with approved material for the periods
specified in the Contract. If settlement of surcharged fill results the Contractor shall bring the resultant level up to
formation level with acceptable material for use in fill.
Settlement Period
Where settlement period is specified in the Contract, the embankment shall remain in place for the required settlement
period before excavating for abutment, wing wall, retaining wall, footings, etc., or driving foundation piles. The duration
of the required settlement period at each location shall be as provided for in the Contract or as directed by the Engineer.
Plying of Traffic
Construction and other vehicular traffic shall not use the prepared surface of the embankment and/or sub-grade without
the prior permission of the Engineer. Any damage arising out of such use shall, however, be made good by the Contractor
at his own cost as directed by the Engineer.
Surface Finish and Quality Control of Work

the help of a motor grader of adequate capacity, its blade having hydraulic controls suitable for initial
adjustment and for maintaining the required slope and grade during the operation, or other means as approved
by the Engineer.
Manual mixing shall be permitted only where the width of laying is not adequate for mechanical operations as in
small sized jobs. The equipment used for mix-in-place construction shall be a rotavator or similar approved
equipment capable of mixing the material to the desired degree. If so desired by the Engineer, trial runs with the
equipment shall be carried out to establish its suitability for the work.
Moisture content of the loose material shall be checked in accordance with IS:2720 (Part 2) and suitably adjusted
by sprinkling additional water from a truck mounted or trailer mounted water tank and suitable for applying
water uniformly and at controlled quantities to variable widths of surface or other means approved by the

moisture content corresponding to IS: 2720 (Part 8). While adding water, due allowance shall be made for
evaporation losses. After water has been added, the material shall be processed by mechanical or other
approved means like disc harrows, rotavators until the layer is uniformly wet.
Immediately after spreading the mix, rolling shall be done by an approved roller. If the thickness of the
compacted layer does not exceed 100 mm, a smooth wheeled 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 a vibratory roller of
minimum 80 to 100 kN static weight capable of achieving the required compaction. Rolling shall commence at
the lower edge and proceed towards the upper edge longitudinally for portions having unidirectional cross fall or
on super elevation. For carriageway having cross fall on both sides, rolling shall commence at the edges and
progress towards the crown.
Each pass of the roller shall uniformly overlap not less than one-third of the track made in the preceding pass.
During rolling, the grade and cross fall (camber) shall be checked and any high spots or depressions which
become apparent, corrected by removing or adding fresh material. The speed of the roller shall not exceed 5 km
Rolling shall be continued till the density achieved is at least 98 percent of the maximum dry density for the
material determined as per IS:2720 (Part 8). The surface of any layer of material on completion of compaction
shall be well closed, free from movement under compaction equipment and from compaction planes, ridges,
cracks or loose material. All loose, segregated or otherwise defective areas shall be made good to the full
thickness of layer and re-compacted.

Construction Operations:-
Preparation of Base
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 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 rolled.
Ahmedabad Municipal Corporation
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 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.
