The cumulative pavement damage effects of all highway vehicles are usually quantified using axle load equivalency factors. The existing axle load equivalency factors depend on, among other variables, pavement type and thickness. This means that the axle factors and consequently the number of equivalent axle loads change along a highway corridor as the construction of the pavement changes, even when the traffic loads do not change. General axle load equivalency factors that are independent of pavement-related variables and axle configurations and have a magnitude similar to the AASHTO axle factors are proposed. The general axle factors can simplify the management of pavement traffic load data and are suitable for routine pavement design purposes. Analysis of errors in prediction of cumulative equivalent axle load applications also suggests that the largest uncertainty is due not to the errors associated with axle load equivalency factors but to other variables, such as traffic volume estimates and axle weights.
