Question: The soil at a borrow area is at moisture content of 10.5% and unit weight of 17.5 kN/m3. This soil is used in the construction of a compacted road base where the dry unit weight is 18.5 kN/m3 and the moisture content is 14.0%.
a) If the finished volume of the road base is 135,000 m3, what would be the volume of the soil removed from the borrow pit?
b) How much water would be added to the soil from the borrow pit?
c) What would be the weight of borrow pit soil and the compacted soil?
