Discrete Element Simulations of 4-Point Bending Fatigue Tests of Asphalt Concrete Samples Reinforced by Fiberglass Grids
This paper studies the fatigue damage of asphalt concrete (AC) under strain controlled load. The 3-phase fatigue life is reproduced by the proposed simulations combining a 2-phase fatigue damage law and the discrete element method (DEM) characterized by discrete force and displacement on each contact. The simulation results present good agreements with experiments after the parameter calibrations. The reinforcement effect of fiberglass grids on the fatigue life of asphalt concrete is studied with 4-point bending (4 PB) fatigue test. These preliminary results comparing simulations and experiments show the consistency of the proposed 2D model on describing part of the interactions between grids and asphalt concrete.
