Chapter 6 | Soil Compaction 6.11 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 specific gravity of soil solids, and the cost per cubic meter for moving the soil of the four borrow pits, as described in the following table. The void ratio, to the proposed construction site are provided in the table. a. Determine the volume of each borrow pit soil required to meet the spec- ification of the embankment site. b. Make the necessary calculations to select the borrow pit which would be most cost-effective.
