Damage to pavement

The life of a pavement is measured by the number of passes of a vehicle axle. It may be evaluated using the Load Equivalency Factor, which states that the damage by the pass of a vehicle axle is proportional to the 4th power of the weight, so a ten-ton axle consumes 10,000 times the life of the pavement as a one-ton axle. For that reason, loaded trucks cost the same as thousands of cars in pavement costs, and are subject to higher taxes and highway tolls.
