An embankment for a highway 30m wide and 1.5m thick is to be constructed from a sandy soil. Trucked in from a borrow pit. The water content if the sandy soil in the borrow put is 15% and its voids ratio is 0.69. Specifications require the embankment to be compacted to a 7 unit weight of 18 KN m ¹ . Determine, for 1km length of embankment, the dry unit weight of the sandy soil form the borrow put required to constrict the embankment assuming G = 2.70. the number of 10 m3 truckloads of sandy soil required to constrict the embankment, the weight of water per truck load of sandy soil, and the degree of saturation of the in sate sandy soil.
