Q$1.(10$ Points$)$

Estimate the equivalent $18-$kip single $-$axle load applications $($ESAL$)$ for a four lane pavement $($two lanes in each direction$)$ of a rural interstate highway with a truck count of $1000$ per day, an annual grown rate of $5\%,$ and a design life of $20$ years.

Q$2.(20$ Points$)$

A pavement of a rural $4-$lane arterial highway is subjected to the single$-$axle loads shown below. Determine the ESAL for a design period of $20$ years for

$($a$)$ Flexible $($Assume $p_i=2\mathrm{.}5$ and $SN=5)(10$ Points$)$

$($b$)$ Rigid Pavements $($assume $D=9").(10$ Points$)$

Assume a traffic growth rate of $2\%.$
