Your company has won a contract to provide and compact the fill material for an earth levee with the dimensions shown in Problem No.1 Figure (next slide). The levee fill is a silty clay soil to be compacted to at least 95% of maximum standard proctor of Ydry: 16.65 kN/m³ at an Optimum Moisture Content (OMC) of 18%. Your borrow pit has a silty clay with an in-situ moist density of 17.60 kN/m³ at 18% moisture content, and G = 2.68. When the soil is excavated and loaded on to your trucks, the void ratio of material is e = 1.47. Your trucks can haul 11.5 m³ of materials per trip. Determine the volume of fill required for the levee

Your company has won a contract to provide and compact the fill
material for an earth levee with the dimensions shown in Problem
No.1 Figure (next slide). The levee fill is a silty clay soil to be
compacted to at least 95% of maximum standard proctor of Yary
16.65 kN/m³ at an Optimum Moisture Content (OMC) of 18%. Your
borrow pit has a silty clay with an in-situ moist density of
17.60 kN/m³ 18% moisture content, and Gs = 2.68. When the
soil is excavated and loaded on to your trucks, the void ratio of
material is e= 1.47. Your trucks can haul 11.5 m³ of materials per
trip.
a. Determine the volume of fill required for the levee.
b. Determine the volume required from the borrow pit.
c. Determine the required number of trucks.
