Truck A has two single axles. One axle weighs 12,000 lb and the other weighs 23,000 lb. Truck B has an 8000-lb single axle and a 43,000-lb tandem axle. A rigid pavement is to be designed to provide a service life of 30 years. The modulus of subgrade reaction is determined to be 300lb/in^3. Reliability is 95%, the overall standard deviation is 0.45, the concrete's modulus of elasticity is million lb/in^2, and the drainage coefficient is 1.0. Which truck will cause more pavement damage on a rigid pavement with a 10-inch slab?
