Your company has won a contract to provide and compact the fill material for an earth levee, with the dimensions shown below. The levee fill is a silty clay to be compacted at least 95% of maximum Standard Proctor of dry unit weight of 106 kN/m³ at an optimum moisture content of 18%. Yours borrow pit has a silty clay with an in-situ density of 112.1 pcf at 18%, and a specific gravity of 2.68. When the soil is excavated and loaded on to your trucks, the void ratio of the material is e = 1.47. Your trucks cam haul 15 cubic yards of material per trip. a -) Determine the volume of fill required for the leave, b -) Determine the volume required from the borrow pit 20 ft 3:1 20 ft 60 ft 20 ft 40 ft 2:1
