Viscoelastic Response of Asphalt Pavements Subjected to Dynamic Loading
Because of the dynamics of vehicle-pavement interaction, the magnitude of the load transferred to the pavement can be significantly higher than that transferred in static conditions. However, the dynamic loading history is usually such that loads of relatively higher magnitude occur over shorter periods of time, and hence have shorter residence times at any given location. While this may not have a consequence on the response of elastic materials, the duration of the loading can significantly influence the response of viscoelastic materials. In this study, a linear viscoelastic model was used to capture the response of the HMA layers to short-duration high-magnitude loads. The resulting response was compared with that obtained by assuming the HMA layers to be elastic. The results show that the strain at the bottom of HMA layer is considerably lower when the viscoelasticity of the pavement layers are taken into account.
