A standard Proctor compaction test in the laboratory on a borrow pit soil

resulted in a maximum dry unit weight of $19$ kN$/$m$3$ and optimum water

content of $11\mathrm{.}5\%.$ The unit weight and water content of the soil in the

borrow pit are $17\mathrm{.}2$ kN$/$m$3$ and $8\mathrm{.}2\%,$ respectively. A highway fill is to be

constructed using this soil. The specifications require the fill to be

compacted to a relative compaction of $95\%$ using the standard Proctor

test. How many cubic meters of borrow pit material is needed for $1$ cubic

meter of highway fill?
