| Abstract: | In this paper, analysis of reinforcement mechanism of glass fiber grid in asphah overlays is made to prevent reflection cracks from developing. The theory study and experiment results show that anti-cracking performances, including ductility and splitting-tensile strain energy, of asphalt mixture reinforced with glass fiber grid are improved effectively both at normal and low temperature. |
