Answer / bijaya kumar behera

ex; water required for 200 mts road??
ans: volume of earth= 200 x 7 x 0 .2 = 280 cum
% OMC = 7 %
After Soil testing NMC = 5% (achived)
So required mc = 7 - 5 = 2 %
for air evaporation add 1%
2+1 = 3 %
water required in earth volume = 280 x 3 % = 8.4 cum
per cum reqd quantity of water 1000 ltr
so total water reqd = 8.4 x 1000 = 8400 ltr

Answer / hiren thakkar

For and e.g. Qty of earth work = 9,60,000 cum.
% OMC = 12.5
After soil test % OMC comes as per laboratory test = 8 to
9% ( say 8.9 %).

So OMC now =12.5 -8.9 = 3.6 % ( usually Depending on the
soil type, an in-situ moisture content deviating 2% to 4%
from the optimum moisture content as determined from the
Proctor test, may create impossible conditions to achieve
the required compaction).i.e 3.6 % is ok.

now Qty = 9,60,000 x 3.6/100 = 34560 cum or 34560000 lit
water required.

Now add evaporation losses @ 10%.

so now the exact vol of water required for compaction of
earth work is 3,80,16,000 lit.

Answer / hiren n. thakkar

Determination of Water to Be Added
If the moisture content of the soil is less
than optimum, the amount of water to be
added for efficient compaction is generally
computed in gallons per square yards. The
computation is based on the dry weight of soil
contained in a compacted layer. For example,
assume that the soil is to be placed in 6-inch,
compacted layers at a dry weight of 120 pcf.
The moisture content of the soil is determined
to be 5 percent while the OMC is 12 percent.
Assume that the strip to be compacted is 40
feet wide. Compute the amount of water that
must be added per 100-foot station to bring
the soi1 to optimum moisture. The following
formula applies:

{Desired Density (pcf)x W(desired)-W (actual)/100}x Vol.
(cu.ft)x 1gal./8.33lb

Substituting in the above formula from the
conditions given:

[120(pcf)x 12-5/100]x 100ft x 40ft x 0.5ft x 1gal/8.33lb

= 2017 gal/station.

If either drying conditions or rain conditions
exist at the time work is in progress, it may be
advisable to either add to or reduce this quantity
by up to 10 percent.



Substituting in the above formula from the
conditions given:
If either drying conditions or rain conditions
exist at the time work is in progress, it may be
advisable to either add to or reduce this quantity
by up to 10 percent.
