Ques. No$.1.$ A CC pavement is to be designed for a $2$ lane $2$ way national highway in Jammu, for a design life of $25$ Years. Total two way traffic is $2600$ CVPD at the end of construction period. Axle load survey of commercial vehicles indicated that the percentage of front single $($steering$)$ axle, rear single axle, and rear tandem axle are $\backslash (45\backslash \%,20\backslash \%\backslash ),$ and $\backslash (35\backslash \%\backslash )$ respectively. The percentage of commercial vehicles with spacing between the front axle and first rear axle less than $4\mathrm{.}5$ m is $\backslash (55\backslash \%\backslash ).$ Traffic count indicates that $\backslash (60\backslash \%\backslash )$ of the commercial vehicles travel during night hours $(6$ PM to $6$ AM $).$ Details of axle load spectrum of rear single and tandem axles are given in Table below. The average number of axle per commercial vehicles is $2\mathrm{.}35.$ Design a PQC layer thickness with tied concrete.
