Description
Summary:The relationships between axle weight and pavement damage are traditionally based on data collected from road tests. The goal of the research presented in this paper is to use available field data to develop nonlinear dynamic simulation techniques for predicting pavement performance. The study provides information on pertinent issues through models of vehicle dynamic loads and their effect on selected pavement structures. The model structure allows estimates of the cracking and failure of rigid pavement slabs and joints as a result of repeated applications of the dynamic loads simulated for specific gross vehicle loads and tractor-trailer configurations. A preliminary pavement consumption model is proposed that gives reduced equivalent pavement thickness as a function of number of vehicle passes.
