Analysis of the Mechanical Impact of High-Modulus Asphalt Concrete on Road Structure

Abstract:

In order to study the rutting problem of asphalt pavement, this paper sets up a three-dimensional model of asphalt pavement with finite element. By analyzing the mechanical response of high-modulus asphalt concrete at different layers, this paper finds out the layer set of high-modulus asphalt concrete. At the same time, it further analyzes the influence of the modulus’ size and thickness of the high-modulus asphalt concrete on the load-carrying capability of road structure. The results show that high-modulus asphalt concrete can significantly restrain rutting problem and the recommend ideal modulus is between 2000MPa and 2500MPa; the ideal thickness ranges from 5cm to 7cm.
