a) The soil from a borrow pit is at a total density of 1.8 t/m3
and a water content of 12%. It is desired to construct a road
subgrade with a compacted total density of 2 t/m3 at a water
content of 17%. Determine the quantity of soil (dry mass in tonnes)
to be excavated from the barrow pit and the amount of water (in
litres) to be added for every 1 m3 of compacted soil in the
embankment. (Assume the specific gravity of soil is 2.65).
b) Explain the relative benefits of using stone mastic asphalt and
open graded asphalt in pavement.

A cubical tank has sides of 4.5m which contains three immiscible liquids at same depths. A water upto a height of 1.5m above the base, An immiscible liquid of specific gravity 0.9 is filled in between both liquids (mid-portion) upto 1.5m height, the upper remaining part is filled with oil of specific gravity 0.79. Calculate (i) The value of pressures at the top, at the interface points and at bottom on one side of the tank (ii) The position of center of pressure for one side of the tank. (iii) What suggestions would you give to your client on the basis of obtained results? (iv) Pressure distribution Diagram
