A six$-$lane divided highway is to be designed to replace an existing highway. The present AADT $($both directions$)$ of $5,900$ vehicles is expected to grow at $5$ percent per annum. Assume $SN=4$ and $p_t=2\mathrm{.}5.$ The percent of traffic on the design lane is $45$ percent. Determine the design ESAL if the design life is $20$ years and the vehicle mix is as follows. $($Assume the contribution of passenger car traffic to the total ESAL is negligible. Use single$-$axle load equivalency factors for $2-$axle and $3-$axle trucks.$)$

Passenger cars $(1,000l\frac{b}{a}$xle$)=62\%$

$2-$axle single$-$unit trucks $(5,000l\frac{b}{a}$xle$)=26\%$

$3-$axle single$-$unit trucks $(7,000l\frac{b}{a}$xle$)=12\%$

Total ESAL $=$

Your response differs from the correct answer by more than $100\%.$
