An embankment for a highway 30 m wide and 1.5 m in compacted thickness is to be constructed from sandy soil trucked from a borrow pit. The water content of the sandy soil in a 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 1-km length of embankment, the ff; (g) The weight of water per truckload of sandy soil. (h) The degree of saturation of the sandy soil in situ. The dry density of sand with a porosity of 0.387 is 1600 kg/

An embankment for a highway 30 m wide and 1.5 m in compacted thickness is to be constructed from sandy soil trucked from a borrow pit. The water content of the sandy soil in a 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 1-km length of embankment, the ff;
(g) The weight of water per truckload of sandy soil.
(h) The degree of saturation of the sandy soil in situ.
The dry density of sand with a porosity of 0.387 is 1600 kg/m3. Find the following;
(i) The void ratio of the soil.
(j) The specific gravity of the soil solids.
