The soil for backfilling comes from a borrow pit. The water content of the soil in the borrow pit is 15% and its void ratio is 0.69. The swell index index is 1.2. The specification requires the backfill material to be compacted to a dry unit weight of 16 kN/m^3 1. What is the dry unit weight of the borrow pit material? 2. What is the volume of the borrow pit soil required? 3. What is the volume of borrow pit material required considering swell?
