Abstract (EN): In this article, the numerical modelling of a pavement structure, tested in the accelerated pavement testing facility in Centro de Estudios y Experimentation de Obras Publicas-CEDEX is presented, with axissimetric and 3D models. For each model two hypotheses of analysis were considered: 1) all materials are elastic linear and 2) bituminous material is viscoelastic with granular materials and subgrade elastic linear. The finite element package used is DIANA, based on the Displacement Method. The numerical results are subsequently compared with experimental ones. For the covering abstract see ITRD E121480.
