The material in Problem 23 has a shrinkage of 94 percent and a swell of 25 percent. Determine the net import or export required for the project and the number of 10-cubic-yard truckloads needed to haul the material to or from the project.

What will be an ideal response?


Convert the fill from compacted cubic yards to bank cubic yards:

Required bcy = 298 ccy / 0.94 = 317 bcy

Find the net export:

Export (bcy) = 1,233 bcy – 317 bcy = 916 bcy

Export (lcy) = 916 bcy × (1 + 0.25) = 1,145 lcy

Trucks = 1,145 lcy / 10 lcy per truck = 115 trucks
