This communication concerns analysis of the behavior of flexible pavements using an elastic-viscoplastic constitutive relation for the asphalt concrete. The numerical model takes into consideration the influence of the temperature on the behavior of the asphalt. The paper presents successively the constitutive relation used in the analysis, the validation of the numerical model on field tests and a sensitivity analysis of the behavior of pavements to a variation of the material properties, the temperature and the period of loading. Numerical results show that the elastic-viscoplastic model reproduces well the behavior of flexible pavements and that the increase in the temperature affects significantly the deformation of the pavement.
