Example $2\mathrm{.}2$

Soil has been compacted in an embankment at a bulk density of $2\mathrm{.}15M\frac{g}{m}3$ and a water content of $12\%.$ The value of Gs is $2\mathrm{.}65.$ Calculate the dry density, void ratio, degree of

saturation and air content. Would it be possible to compact the above soil at a water content of

$13\mathrm{.}5\%$ to a dry density of $2\mathrm{.}00M\frac{g}{m^3}?$
