An embankment for a highway 30 m wide and 1.5 m in compacted thickness is to be constructed from a sandy soil trucked from a borrow pit. The water content, w, of the sandy soil in the borrow pit is 15% and its void ratio, e, is 0.69. The specification requires the embankment be compacted to a dry unit weight of 18 kN/m^3. Determine, for 1 km length of embankment, the following:
a) The weight of the sandy soil from the borrow pit required to construct the embankment.
b) The number of 10.0 m^3 truckloads of sandy soil required for the construction.
c) The weight of water per truckload of sandy soil.
d) The degree of saturation of the sandy soil in the borrow.
