The pavement that need to be constructed is a six-lane divided highway. The present AADT (both directions) of 6000 vehicles is expected to grow at 5% per annum. The percent of traffic on the design lane is 45%. Determine the design ESAL if the design life is 20 years and the vehicle mix is: Passenger cars (1000 lb/axle) 60% 2-axle single-unit trucks (5000 lb/axle) = 30% 3-axle single-unit trucks (7000 lb/axle) 10% %3D Dosign the navement (with the design ESAL calculated in auestion 3a)
The following figure shows concrete pavement with the layer thickness and elastic modulus as indicated. Assume modulus of rupture of 650 psi, load transfer coefficient of 3.2, serviceability loss from 4.5 to 2.5, and drainage coefficient of 0.9. The bedrock depth and loss of support is not considered for the subgrade. Use the design equation or monograph with 50% reliability to solve the following: 1) Determine the number of ESAL that the pavement can carry before failure. 2) If the daily traffic has 1080 single axles (20-kip), 400 single axles (24-kip), and 680 tandem axles (40-kip), and the annul traffic is the same over the design period, how many years would the concrete pavement last before failure? 8-inch Portland Cement Concrete Ec=4×106 psi 8-inch Granular Subbase Ec=30,000 psi Subgrade Mr = 5000 psi
