Abstract

Aiming at the common asphalt pavement structure combination, large general finite element software is used to build the three-dimensional model based on the multi-layer elastic system theory. The pavement structure vertical displacement and stress are analyzed entirely under the moving load. The results show: The faster the load speed, the fluctuation displacement and maximum displacement in pavement structure layer is smaller. The load moving speed has little effect to the maximum vertical stress of the structure layer, but the greater the speed, the subsequent stress fluctuating is more furiously. In the same speed, each node equivalent stress and time relationship curve is very similar, and the change rule almost identical. The above shows the influence of dynamic load on the pavement structure layer can not be ignored.
