Example A main multi-lane highway is to be constructed on a new alignment. The traffic forecast indicated that AADT= 12000 veh/day, with following vehicles mix and axle load: 50% Passenger car unit, two single axles, axle load=2kip/axle 33% light weight truck, two single axles, axle load=6kip/axle 17% medium weight trucks, three single axles, axle load=10kip/axle 1- Find the ESWL daily if you know that D.D=50% and assume SN=3 for equivalence factor calculation. 2- Use the same layer in the previous exam and design pavement thickness.
