- An existing rural 4-lane highway is to be replaced by a 6-lane divided expressway (3 lanes in each direction). Traffic volume data on the highway indicate that the AADT (both directions) during the first year of operation is 24,000 with the following vehicle mix and axle loads. Passengercars=50percent 2-axle single-unit trucks (12,000lb/axle)=40percent 3-axle single-unit trucks (16,000lb/axle)=10percent The vehicle mix is expected to remain the same throughout the design life of 20 years, although traffic is expected to grow at a rate of 3.5 percent annually. Using the AASHTO design procedure, determine the minimum depth of concrete pavement required for the design period of 20 years.

The present AADT (both directions) of 6000 vehicles is expected to grow at 5% per annum. Assume SN = 4 and pt = 2.5. The percent of traffic on the design lane is 45%. 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% Design a suitable pavement consisting of an asphalt mixture surface with an elastic modulus of 250,000 lb/in2, a granular base layer with a structural coefficient of 0.14 on a subgrade having a CBR of 10. Assume all mi values = 1. Use a reliability level of 85%, a standard deviation of 0.45, and a design serviceability loss of 2.0.arrow_forwardDiscuss about the effect of overloading of trucks to the pavement condition.arrow_forward
