Abstract

The study is focused on the structural performance of conductive asphalt pavement embedded with exchanger tubes, using the finite element method. The pavement structure was modeled as a three-dimensional four-layer stratum using ABAQUS finite element suite. Viscoelastic response models of the asphalt concrete were properly established by using the Prony series. The developed response models were used in finite element simulations on the conductive asphalt pavement. The model of pavement embedded with different types of tubes was subjected to moving load. When the material stress or strain in the layer is computed, the design life can be predicted by using a fatigue model. Finally, the simulating method of the conductive asphalt pavement embedded with tubes was put forward and the study will provide road structural engineers with some design basis.
