Traffic studies were conducted on a 4-lane divided flexible pavement highway and the average CVPD was found to be 3500 in one direction. The growth rate is 5%, VDF is 4.5 and the estimated time of completion of the overlay is 2 years. The BBD studies yielded the characteristic deflection to be 2.4 mm. What would be the thickness of the overlay if it to be designed for 10 years?
