A mass of soil coated with thin layer of paraffin wax weighs 690.6 g and the soil alone weighs 683 g. When the sample is immersed in water, it displaces 350 ml of water. The specific gravity of the soil is 2.73 and that of wax is 0.89. Find out void ratio and degree of saturation if it has got water content of 17%.

The soil fill for a road embankment is to be compacted in place to a void ratio of 0.7. Ifthe void ratio of the borrow pit soil is 1.2, how many cubic metres of compacted fill can be placed in theembankment per 1000 cubic metres of borrow materials? If no water is either added or lost during theplacement of the fill, what would be the percentage change in the degree of saturation of the soil? Thecompacted fill is not fully saturated.
