Question

A proposed embankment fill requires 7500 m3 of compacted soil. The void ratio of the
compacted fill is specified as 0.7. Soil can be transported from one of the four borrow
pits, as described in the following table. The void ratio, specific gravity of soil solids,
and the cost per cubic meter for moving the soil to the proposed construction site are
provided in the table.
a. Determine the volume of each borrow pit soil required to meet the specification of
the embankment site.
b. Make the necessary calculations to select the borrow pit which would be most costeffective.
