Summary

This paper presents the modeling of a multilayered structure for the purpose of simulating the dynamic behavior of a flexible airfield pavement under the effect the loading applied by a non-destructive pavement assessment device: the heavy weight deflectometer (HWD). A Huet-Sayegh model is considered to describe the mechanical behavior of bituminous layers. The benefits of viscoelastic behavior in bituminous materials are highlighted using this modeling approach.
