摘　　要：对玻纤格栅在沥青罩面层中抑制反射裂缝的机理进行了理论分析,通过室内劈裂试验,分别从延性和劈裂应变能的角度验证了玻纤格栅沥青混合料在常温及低温下抗裂性能方面的改进。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.
