The marginal cost for pavement renewal - a duration analysis approach
The wear and tear of an extra vehicle that uses a road results in advancement of future repavements. This increases the present value cost of these repavements, which is interpreted as the marginal cost. Using a large data set covering all pavement renewals on the Swedish national road network since the 1950s, deterioration elasticities that express the relation between traffic intensity and the pavement lifetime are estimated and are then used to compute marginal costs. The elasticities for heavy goods vehicles and passenger cars are found to be small and marginal costs are accordingly low.
