Mechanical properties of fiber-reinforced asphalt concrete: Finite element simulation and experimental study

Abstract Polymer fiber reinforcement can elevate the pavement performance indicators of asphalt concrete, including low temperature crack resistance, high stability, and water stability. Fiber-reinforced concrete (FRAC) is a suitable solution to improve road concrete. However, mechanism parameters in has still not been introduced. Herein we studied influence geometry characteristics on improving mechanical properties through numerical simulation. The finite element method (FEM) was used establish an elastoplastic mesoscopic model for indirect tensile test mixtures via ABAQUS. best length, volume ratio, diameter, modulus were confirmed based simulated results. Furthermore, tests undertaken prove polyacrylonitrile (PAN) polyvinyl alcohol (PVA) FRAC’s splitting This study fills gap between theoretical simulations laboratory experiments, it promising engineered FRAC performance.
