In this paper, the finite element method was used to analyze the influence of principal stress distribution on asphalt pavement. Three-dimensional finite element model under double-round uniform load was established for multi-layer asphalt pavement with flexible base and stress components of each node were analyzed based on Drucker-Prager (D-P) criterion. A new index, asphalt pavement potential damage index (APPDI), was proposed. Two conclusions were obtained as follow: firstly, the principal stress composition has a great influence on asphalt pavement damage. Secondly, the comparative analysis of the maximum APPDI and stress in each layer indicated that APPDI could be used as the damage evaluation index of pavement structures.
