Construction Methods : 

Diversions : If diversions, barricading and signals for day and night are necessary, they shall be 

provided without any extra cost. 

Preparing the Ground for Laying Bank : Before any material is laid for the embankment the ground 

shall be cleared of all rubbish, removing bushes, etc., and the holes, if any, filled up. When the 

embankment is to be laid on hillsides or slopes, the existing slopes shall be ploughed deeply. If the 

cross slopes are steeper than 1 in 3, steps with reverse slope shall be cut into the slopes to give 

proper hold and seating to the bank as directed by the Engineer-in-Charge. On surfaces flatter than 1 

in 15, no special surface treatment such as cutting steps shall be necessary. The top 15 cm of soil 

shall be scarified and watered as directed and compacted to the same density as specified for the 

embankment before any material is laid for the Bank-work. 

When the embankment is to be placed over an existing road, which is within 15 cm of the finished 

formation, the road or other hard surface shall be scarified to a minimum depth of 15 cm for which 

payment shall be made separately under relevant item of road excavation. 

The rate for embankment includes all the operations for preparing the bed for laying the embankment 

material. 

Laying the Bank : Embankment material shall be placed in successive horizontal layers of 20 cm to 

30 cm thickness extending to the full width of the embankment including the slopes at the level of the 

particular location and 30 cm more on both sides to allow compaction of the full specified section. The 

extra loose stuff at the edges shall be trimmed after completion of the embankment work without extra 

cost leaving the correct section fully compacted. Keeping width of the bank initially less and widening 

it later by dumping loose earth on the slopes shall not be permitted as the additional width and slopes 

may remain loose and un compacted and may not have been compacted as earlier carried out work. 

Similar procedure to extend the embankment by dumping the material longitudinally shall also not be 

allowed. 

When boulders, broken stones, and similar hard materials are mixed up with the embankment 

materials, care shall be taken to see that they are distributed uniformly in to the embankment and that 

no hollows are left near them. No stone or hard material shall project above the top of any layer. Each 

layer of embankment shall be watered, leveled and compacted as specified, before the succeeding 

layer is placed. The surface of the embankment shall, at all times during construction, be maintained 

at such a cross fall to shed water and prevent ponding. If bridges and culverts on the road are not 

completed in advance of embankment work, a length of 15 m bank shall be left on each side of the 

structure and these lengths shall dealt with later for placing the embankment work. The contractor 

shall construct temporary diversion road till the work of culverts and bridges are completed and all 

type of traffic is allowed to be passed on these bridges and culverts. The camber stipulated shall be 

provided in the embankment only and shall not be adjusted in metalling. 


Executive Engineer



Protection : Proper care shall be taken to ensure that the method of operation and compaction of the 

bank-work does not cause damage or undue strain to any structural element. Embankment over and 

around bridges or culverts shall be of approved materials and carefully placed and compacted. The 

contractor shall take all precautions necessary for the protection of the bank-work by diversions of 

streams, local surface drainage, rain water, etc. likely to damage the bank. Any damage to the 

embankment-work due to no protection or inadequate protection shall be made good by the contractor 

at his own cost. Conveyance of materials shall not cause obstruction or nuisance to the nearby 

property owners and traffic. 

Finishing : The embankment shall be finished and dressed smooth and even in conformity with the 

alignment, levels, cross-sections and dimensions shown on the drawing with due allowances for 

shrinkage. On curves, sections shall be provided with super elevation and increased widths as shown 

on the plans or directed by the Engineer-in- Charge. All damages caused by rain, flood or any other 

reasons shall be made good in the finishing operations without any extra cost by the contractor. The 

road land width shall be cleared. 

Maintenance : The contractor shall be responsible for maintaining the work satisfactorily at his own 

cost till the completion of the defect liability period as specified in the contract agreement. 

Test : 

(a) Tests shall be made to determine the required density of the material to be used by the Proctor 

Density Method before starting the work. 

(b) Density tests shall be carried out for the bank-work during the progress of the work. One set of 

three core samples for every 4,000 sqm area of each layer of bank-work shall be taken and tested. 

The average density shall be more than 95% of the standard proctor density. A deviation of 80 kg per 

cum for fine and 160 kg per cum for coarse grained murum shall be permitted in dry density in 

individual sample if the average density reached up to 95% of standard proctor density for each set. 

(c) The required number of CBR tests and plasticity index tests for murum shall be carried out as 

directed by the Engineer-in-Charge. The murum to be used for embankment shall be of following 

standards. 

1) Before murum is brought to side, it shall be tested the laboratory for its soak CBR. For this the 

sample must be collected from the quarry itself by the Deputy Engineer. The laboratory soak CBR 

value should be more than 12%. When the murum is the brought to site its soak CBR shall be 

checked by MIDC in laboratory was ascertain the procurement of same quality of murum. 

In addition to soak CBR the murum shall be tested for its liquid limit, plasticity index, 

maximum dry density and optimum moisture content. The murum shall be of following standards. 

a) Liquid limit : Not more than 25. 

b) Plasticity Index : Not more than 6. 


Executive Engineer



All these test shall be conducted according to IS-2720. 

When the murum is spread on side, watered and compacted for embankment it shall 

be tested for field soak CBR and test shall be carried out at random location for every 4000 sqm. area 

of embankment. The field dry density and water content shall be checked to ascertain the field 

compaction for the same sample from the same location of field CBR test. The field soak CBR value 

for the murum shall be more than 8% in any case. 

If the murum is brought to site with specified test, shall not be paid unless its quality is 

evaluated by the laboratory test in respect of plasticity index, liquid limit and laboratory soak CBR. 

The necessary test shall be carried out as per respective IS codes as under. 

1) IS – 2720, Part-5: For liquid limit and plasticity index. 

2) IS-2720, Part-8 : For OMC and MDD test.
