In its natural state the soil in a borrow pit, the total (moist) unit weight is 120 lb/ft³, and the water (moisture) content is 20 %. The result of the Modified compaction test of the soil of the borrow pit is given in the figure below. The soil from the borrow pit will be used to construct a compacted fill. The construction of the fill requires 10,000 ft³ of compacted soil. The specifications required that the compaction of the fill be performed at the optimum moisture content to obtain the maximum dry unit weight for fill. How much (volume in ft³) must be excavated from the borrow pit? Dry unit weight (lb/ft³) 107 106 105 104 103 102 8 12 w (%) 16 20 24
