Soil is to be excavated from a borrow pit which has a density of 1.75 g/cc and water content of 12%. The specific gravity of soil particles is 2.7. The soil is compacted so that water content is 18% and dry density is 1.65 g/cc. For 1000 cu.m of soil in fill, estimate (i) the quantity of soil to be excavated from the pit in cu.m; and (ii) the amount of water to be added. Also determine the void ratios of the soil in borrow pit and fill.
