Effect of Bonding Condition between Asphalt Layers on Behavior of Pavement

Most of asphalt pavement designs assume that adjacent asphalt layers are fully bonded together and no displacement is developed between them. However, full bonding is not always achieved and a number of pavement failures have been linked to poor bond condition. The pavement structure mechanical responses under traffic considering the actual bonding condition between asphalt layers were studied in this paper. A mechanical model was built by the using finite element program ABAQUS to analyze the effect of the interface contact condition on the behavior of asphalt pavement. The analytic results show that the technique of spreading tack coat over the underlayer can effectively decrease the tensile stress at the bottom of asphalt layer, thereby reducing the generation and development of cracks. The discontinuities between base-to-asphalt layers can increase the rutting of asphalt pavement, but the discontinuities between asphalt-to-asphalt layers can't increase the risk of rutting.
