Question $2$

A rectangular ditch with a width of $2\mathrm{.}0m,$ a height of $2\mathrm{.}75m$ and a length $6\mathrm{.}5km,$ will be filled with SSD

coarse aggregates. Given that the unit weight of the aggregates is $1780k\frac{g}{m^3}$ and SSD specific gravity is

$2\mathrm{.}68,$ determine the following:

a$)$ The SSD weights of aggregates particles needed to fill the trench

b$)$ The SSD weights of aggregates needed to fill the trench if the aggregates were compacted with

absolutely no air between them

c$)$ The weight of the aggregate particles needed if the aggregates have $1\mathrm{.}5\%$ surface moisture

d$)$ The weight of the aggregate particles needed if the aggregates have $0\mathrm{.}95\%$ saturation potential
