Geotechnical Problem $4$

Two potential sites are being considered for the quarry. At the first site, the soil has a dry unit weight of $1\mathrm{.}8$

ton $\frac{?}{m^3}$ and a degree of saturation of $40\%.$ At the second site, the soil has a dry unit weight of $1\mathrm{.}7to\frac{n}{m^3}$

and a degree of saturation of $60\%.$ The construction site requires $10,000m^3$ of compacted soil, with a dry

unit weight of $1\mathrm{.}75to\frac{n}{m^3}$ and a degree of saturation of $60\%.$

The cost of the quarry material is based on the volume removed from each site, with a unit price of $$3\mathrm{.}00$

per cubic meter for the material and $$4\mathrm{.}00$ per cubic meter for transportation. Additionally, material that

requires more water incurs an extra $$5\mathrm{.}00$ per cubic meter. Assume the specific gravity of solids $($Gs$)$ is

$2\mathrm{.}65.$

Calculate the cost of material from each site. Which site would you choose?
