An embankment for a highway 30m wide and 1.5m in compacted thickness is to be constructed from a sandy soil trucked from a borrow pit. the water content of the sandy soil in the borrow pit is 15% and its void ratio is 0.69. the swell index is 1.2. the specification requires the embankment to be compacted to a dry unit weight of 18kn/m^3. determine, for a 1km length of embankment, the following:
a) the weight of sandy soil from the borrow pit required to construct the embankment.
b) the number of truckloads of sandy soil required for the construction. the full capacity of each truck is 22.2m^3, and local government regulations require a maximum loaded capacity of 90%.
c) the weight of water per truckload of sandy soil.
d) the degree of saturation of the sandy soil insitu.
