6.6 The in situ moist unit weight of a soil is 17.3 kN/m³ and the moisture content is 16%. The specific gravity of soil solids is 2.72. This soil is to be excavated and transported to a construction site for use in a compacted fill. If the specification calls for the soil to be compacted to a minimum dry unit weight of 18.1 kN/m³ at the same moisture content of 16%, how many cubic meters of soil from the exca- vation site are needed to produce 2000 m³ of compacted fill? How many 20 ton truckloads are needed to transport the excavated soil?
