摘　　要：土工合成材料加筋沥青混凝土路面结构可以提高其疲劳寿命、抗反射裂缝和抗高温车辙能力,成为沥青路面路用技术性能改善的一个有效途径。通过室内试验系统研究了无加筋层、中间加铺玻纤土工格栅或聚酯玻纤布加筋沥青混凝土的低温抗裂性、高温稳定性和抗疲劳性能。试验结果表明,聚酯玻纤布加筋结构具有较好的低温抗裂性能,而玻纤格栅加筋结构的高温稳定性较好。The asphalt concrete pavement structure reinforced with synthetics can improve the fatigue life, reflective crack resistance and high temperature rut resisting ability. This technique has become an effective way for improvements of road performance of the asphalt pavement. The laboratory test of low temperature resistance, the high temperature stability and anti-fatigue performance are done with the ordinary asphalt concrete pavement structure, reinforced with glass fiber geogrid or polyester glass fiber cloth glass. The test results show that polyes- ter glass fiber cloth reinforcing structure has good low temperature crack resistance energy, while glass fiber rein- forcement grid structure has good high temperature stability.
