Traffic studies were conducted on a 4-lane flexible pavement highway and the average CVPD was found to be 3000 in one direction. The growth rate is 7.5%, VDF is 4.5 and the estimated time of completion of the overlay is 2 years. The BBD studies yielded the mean rebound deflection to be 3 mm when tested at 35°C in the monsoon time and the standard deviation is found to be 0.22 mm. What would be the thickness of the overlay if it to be designed for 10 years?
