Summary

This paper is concerned with the modeling of the behavior of a flexible pavement under vehicule or impact forces. The model is built with the finite element method and allows to take into account the viscoelasticity which characterise the bituminous materials. The complex modulus of these materials, depending on frequency and temperature, is integrated to a dynamic frequency calculation. Comparisons are then conducted with a time algorithm and current constant modulus.
