Modeling of rutting in asphalt flexible pavement

André-Gilles Dumont

This paper presents a finite element analysis modeling of rutting. The behaviors of the asphalt concrete is described using an elasto-viscoplastic constitutive relation, while an elastoplastic constitutive relation is used for the lower layers. The model a ...

New Method for Pavement Rutting Prediction

In recent years, pavement rutting rate has increased significantly due to constant traffic intensity increment. These solicitations affect the bituminous layers that can quickly attain their permanent deformation limit resistance. This phenomenon can lead ...
