watering may be necessary. However, in summer months as the loose soil looses moisture at

faster rate compared to borrow area about 10 to 12 % watering may be needed to maintain

the soil moisture within OMC plus or minus 3 percent limit. Assuming seasonal average of 5

to 6 percent watering by weight, daily requirement of water for 734 cum of embankment will be

about 8 tanker loads of 8000 ltrs each.

Deploy 8000 ltr capacity water tanker for 8 hours daily for watering before rolling.

Deploy 5 hp pump for 4 hours.

6. Compaction :

Soil collected for embankment layer gets compacted to some extent during levelling.

Generally 8 to 10 passes of vibratory pad foot roller is adequate for achieving specified density

control of 95 percent.

Effective length of roller drum : 1.90 m

Speed of roller per hour : 4.0 km

Thickness of layer : 0.3 m

Lead for conveyance of soil : Upto 1 km

Speed for loaded tipper under haul road condition : 20 km / hr

Speed for empty tipper under haul road condition : 25 km / hr

Turning and unloading time : 2.00 min

Digging of soil in dump area will be faster compared to borrow area in view of relatively loose

condition of soil. For semi-pervious / pervious soil in dump area the digging cycle can be slightly

more than the digging cycle of impervious soil in dump area. Assume a digging & loading cycle

time at 65 % of borrow area.

Shovel digging and loading cycle per bucket for soil in borrow area : 30 sec

Shovel digging and loading cycle/ bucket in dump area ( 30 x 0.65 ) : 20 sec

1. Quantity of embankment :

In-situ quantity per load for 10 % bulkage of soil ( 5.0 / 1.1 ) say : 4.53 cum

Number of buckets per load ( 4.53 / 0.53 ) say : 8 buckets

Cycle time for loading 8 buckets ( 8 x 20 / 60 ) say : 2.67 min

Round trip cycle time for tipper:

Ideal cycle time of shovel for digging & loading : 2.67 min

Time for 1km haulage under load ( 60 / 20 ) : 3.00 min

Time for turning and un-loading : 2.00 min

Time for 1 km return trip ( 60 / 25 ) : 2.40 min

Time for turning and spotting : 0.50 min

Total : 10.57 min

No.of tippers to match corrected cycle time of shovel (10.57 / 2.67) : 4 Nos

Output of tipper / hr with 50 min working / hr ( 50 x 4.53 / 10.57 ) : 21.40 cum

Output for 4 tippers per day ( 4 x 21.40 x 8 ) say : 685 cum

The output worked out above is the insitu quantity in dump area with 10 % bulkage factor.

The in-situ dry density of soil in borrow area will be generally less than dry density of compacted

embankment. Therefore, the rolled embankment quantity will be slightly less than the borrow

area in-situ quantity. The extent of shrinkage in quantity depends on the degree of compaction

of embankment. For 95 % density control of embankment a shrinkage factor of 5 % is assumed

for use of borrow area soil.

Further, as the insitu density of soil in dump area will be less compared to natural ground due

to bulkage of soil in dump area, for applying the shrinkage foctor it is necessary to convert the

insitu dump area quantity to equivalent borrow area quantity by applying bulkage factor.

Equivalent borrow area quantity for 10% bulkage ( 685 / 1.1 ) 623 cum

Qty of compacted embankment for 5 % shrinkage ( 623 x 0.95 ) : 592 cum

Qty of soil for computing royalty charges @ 1.6 t /cum ( 592 x 1.6 ) : 947 tonnes

2. Stripping of borrow area :

Since the soil is from dump area no stripping is involved.

3. Collection of soil for embankment :

Deploy one 0.50 cum capacity shovel for 8 hours for re-excavation and loading soil.

Deploy 4 tippers of 5.00 cum capacity for 8 hours to convey soil to embankment area.

4. Spreading soil in 250 to 300 mm layer :

Quantity of loose soil to be spread ( 685 x 1.10 ) : 754 cumOutput of dozer for levelling per hour : 250 cum

Time required for levelling 754 cum say : 3.00 hours

5. Watering :

Generally soil in the dump area will be in moist condition. In the beginning of the season no

watering may be necessary. However, in summer months as the loose soil looses moisture at

faster rate compared to borrow area about 10 to 12 % watering may be needed to maintain

the soil moisture within OMC plus or minus 3 percent limit. Assuming seasonal average of 5
