Problem: A 4m high embankment, with a top width of 5m and side slopes of 1:1 has to be constructed by compacting soil from a nearby borrow pit . The unit Wight and natural moisture content of the soil are 1.8t/m3 and 8% respectively. Determine the volume of the earth to be excavated from the borrow pit and the quantity of water to be added to it for every Km of finished embankment, if the required dry density and moisture content of the embankment soil be 1.82gm/cc and 18% respectively, given Gs=2.70
