Earth is required to be excavated from borrow pits for building an embankment. The wet unit weight of undisturbed soil is 1 8 kN/m3 and its water content is 8%. In order to build a 4 m high embankment with top width 2 m and side slopes 1:1, estimate the quantity of earth required to be excavated per meter length of embankment. The dry unit weight required in the embankment is 15 kN/m3 with a moisture content of 10%. Assume the specific gravity of solids as 2.67. Also determine the void ratios and the degree of saturation of the soil in both the undisturbed and remolded states.
