An embankment for a highway 30 m wide and 1.3 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 17% and its void ratio, e, is 0.75. The specification requires the embankment be compacted to a dry unit weight of 19 kN/m^3. Determine, for 3 km length of embankment. Assume Gs = 2.7 a) Compute the volume (m³) of borrow material required b) solve the cost of fill if the earth fill from borrow site costs Pho 150/m³ c) calculate the volume (m³) of borrow material required is the specification required a void ratio of 0.20
