Determine the design esal if the design life is 20 year

Reference no: EM13564983

A six-lane divided highway is to be designed to replace an existing highway. The present AADT (both directions) of 6000 vehicles is expected to grow at 5% per year. Assume SN = 4 and pt = 2.5. 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 (6000 lb/axle) = 25%

3-axle single unit trucks (8000 lb/axle) = 15%
