Example $2$

An excavation is made on a level piece of land, $50$ m long by $25$ m wide and $2$ m deep. The sides are vertical, and it took $1050$ truck$-$loads to remove all the material that came out of the excavation. If each truck load carried a weight of $4950$ kg $,$ and the average moisture content for all the trucks was $10\mathrm{.}25\%$ while the density of the solids was $2650k\frac{g}{m^3},$ calculate the following:

Average bulk densit

Average dry densit!

The volume per truck $$oad

Void rati

Porosity

Air void rati

The number of truck loads required if the soil was saturated and the maximum load per truck was $5000$ kg $(1.$
