The following axle load survey data $($Table $1)$ was obtained from Warangal Highway $($NH$-163),$ connecting Hyderabad to Bhopalpatnam. Determine the Vehicle damage factor $($VDF$)$ for a standard axle load of $80kN.$ Further, it is proposed to widen and strengthen the existing $2$ lanes of the National highway. The traffic in one direction is $2500$ CVPD$.$ The construction period is $02$ years. The design CBR of the subgrade is $5\%,$ and the traftic growth rate is assumed to be $8\%$ for commercial vehicles. The design lifeis $10$ years. Estimate the cumulative standard axles in misa and design the flexible pavement. Show with neat sketches the indicative split of various pavement layers thicknesses.
