Problem $2(5$ points$)$

A $10$ ft wide, $500$ ft long, $2$ ft thick road is being constructed. The maximum dry unit weight

after a Standard proctor compaction test was found to be $112\mathrm{.}1$ pcf at an optimum moisture

content of $10\mathrm{.}5\%.$ The soil from the borrow pit has a total unit weight of $105$ pcf and a moisture

content of $8\mathrm{.}5\%.$ What is the total volume $($cubic ft $)$ of soil that needs to be hauled to the borrow

pit?

How many $15$ cy trucks will be needed for this haul?
