A highway with three lanes in one direction is to be designed to replace an existing highway. The present AADT is 11462 vehicles. Traffic is expected to grow 1% annually. The vehicle mix and axle load are given as follows: Passenger cars = 80% 2-axle single unit trucks (8,000 lb/axle) = 15% 3-axle single unit trucks (22,000 lb/axle) = 5% Excluding passenger cars, the equivalent single axle load for a design life of 20 years and SN = 3 is O 2.66 x 107 O 2.51 x 107 O 2.57 x 107 None of the above
