The design traffic for a minor highway is found to be 10.55 msa. The BBD studies conducted at 30°C on sandy soil with 8% moisture content and an annual rainfall of 1300 mm gave the following results:Rebound deflection values recorded at various points = 1.40, 1.38, 1.49, 1.50, 1.55, 1.44, 1.58, 1.43, 1.33, 1.37 mm
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?
