Abstract:
In this study, an artificial neural network was developed in order to analyze flexible pavement structure anddetermine its critical responses under the influence of standard axle loading. In doing so, more than 10000four-layered flexible pavement sections composed of asphalt concrete layer, base layer, subbase layer, andsubgrade soil were analyzed under the impact of standard axle loading. Pavement sections were analyzed bymeans of multilayered elastic analysis theory and critical responses of pavement including maximumhorizontal principal tensile strain at the bottom of asphalt layer and maximum vertical compressive strain onthe top of subgrade were computed in each case. Then, a Feed-Forward back propagation neural networkwas served to predict these responses. The results show that the artificial neural network can be used as apowerful and accurate tool to predict the critical response of flexible pavements. Application of artificialneural networks for pavement analysis reduces the analysis time and can be used as a quick tool forpredicting fatigue and rutting lives of different pavement sections and so in optimum design of pavementstructure.
