Open publisher page 0 citations

Abstract

Based on the pavement structure three-dimensional model through finite-element calculation software(ANSYS), the representative full-depth asphalt pavement and asphalt pavement with semi-rigid base are analyzed in the aspect of mechanical response under the action of vehicle load. It can be known that the full-depth asphalt pavement is better than the asphalt pavement with semi-rigid in anti-fatigue damage and permanent deformation, what′s more, the lifespan is longer. It has brighter application prospect.
