Anti-Damage Performance of Asphalt Concrete Reinforced with Different Position Grid

Abstract

This paper uses Sidoroff damage model to research asphalt concrete (AC) trabecular tensile damage. Damage factor D is used to estimate the damage degree of AC. And the optimum position of grid overlay is obtained. In order to simulate the trabecula without grid and grid in different position, an AC trabecular bending test model is established in ABAQUS. From the analysis of AC damage, it can retard AC damage efficiently when grid overlay is located on the bottom of trabecula. The results of the research can offer the reference of controlling on damage cracking in the process of design and construction of asphalt pavement.
