$($Assume data whenever is required$)$

An axle load survey was conducted, and the following datn was obtained. The number of vehicles observed $(N)$ is $98,$ the assumed standerd axle load $(W_{nt})$ for single axle single wheel is $6\mathrm{.}6$ tons, single axle dual wheel is $8\mathrm{.}16$ tons, and tandem wxle four$-$wheel is $15\mathrm{.}1$ tons. Calculate the VDF based on the fourth power law using data given in Table $1.$ Further, design the flexible pavement with the following information. It is proposed to widen and strengthen the existing $2$ lanes National highway in front of the NIT Warangal campus. The traffic in one direction is $2500$ CVPD$.$ The construction period is $01$ year. The design CBR of the subgrade is $5\%,$ and the traffic growth rate is assumed to be $8\%$ for commercial vehicles. The design life is $10$ years, and the lane distribution factor is $0\mathrm{.}75.$ Estimate the cumulative standard axles in terms of msa.
