Abstract
For understanding the mechanical behavior of asphalt pavement in the long slope section, this study focuses on the dynamic response of asphalt pavement both considering the horizontal and vertical vehicle load. Firstly, a theoretical model of asphalt pavement was built considering the interface bonding conditions under vertical and horizontal vehicle loads. Then, the performance of the interface bonding between the asphalt layer and the base course layer was presented by a transformation matrix. At last, the analytical expression and numerical solution of the dynamic response in the pavement were obtained by Hankel-Laplace integral transformation. The results of the practical example show that horizontal vehicle load increases the stress on the pavement and affects the distribution of the stress. The bond strength between the asphalt surface layer and the base layer is an important factor affecting the dynamic response of the long longitudinal slope asphalt pavement.
