CTTTT The soil in a borrow pit has a void ratio of 0.90. A fill of volume 20000 m³ has to be constructed with an in place dry density of 19.2 kN/m³. If the owner of borrow pit to be compensated at rate 2.5 per cubic metre of excavation, determine the cost of compensation. Take G = 2.68, Y = 9.81 kN/m³.

A fill having volume of 150000 m³ is to be constructed at a void ratio of 0.8. The borrow pit solid has a void ratio of 1.4. The volume of soil required to be excavated from the borrow pit will be (a) 150000 m³ (c) 250000 m³ (b) 200000 m³ (d) 300000 m³

Determine the porosity if void ratio is 0.45
