This soil is to be excavated and transportedto a construction site for use in a compacted fill. If the specifications call for the soilto be compacted to a minimum dry unit weight of 103.5 lb/ft at the same moisturecontent of 18%, how many cubic yards of soil from the excavation site are needed toproduce 10,000 yd³ of compacted fill? How many 20-ton truckloads are needed totransport the excavated soil?A proposed embankment fill requires 5000 m³ of compacted soil. The void ratio ofthe compacted fill is specified as 0.7. Four borrow pits are available, as described inthe following table, which lists the respective void ratios of the soil and the cost percubic meter for moving the soil to the proposed construction site. Make the necessarycalculations to select the pit from which the soil should be bought to minimize thecost. Assume G, to be the same at all pits.
