Abstract: MTS fatigue loading test and rolling load fatigue loading test were used to evaluate the effect of 8 ordinary anti-cracking materials on the prevention and cure of reflective cracks of composite pavements. And then the best raw materials were selected to develop a new compound material DGQ, which was a kind of high- tensile composite material with cracking resistance performance under heavy load conditions. And its reflective resistance performance and anti-aging performance were verified through indoor MTS fatigue loading test. The results show that：taking final crack loading times as the evaluation criteria, galvanized iron mesh is the material with the best prevention and cure performance of reflective cracks in 8 materials; HZ/ZD-4 is secondary; and fiberglass-polyester cloth and fiberglass geogrid are less effective. The reflective cracking resistance performance and anti-corrosion property of DGQ material developed by galvanized iron mesh and H-typed functional materials are significant, and its construction can be done at room temperature. DGQ material is cost-effective and has good application prospects.

摘要： 首先利用MTS疲劳加载试验和滚动荷载疲劳加载试验,研究了8种普通防裂材料防治复合式路面反射裂缝的效果，然后优选原材料研发出一种适用于重载交通条件的高抗拉复合防裂材料— —DGQ材料，并通过室内MTS疲劳加载试验对其防反性能和抗老化性能进行了验证。结果表明：以终裂疲劳加载次数为评判指标，8种普通防裂材料中镀锌铁网防治反射裂缝的效果最好， HZ/ZD-4型防反技术次之，而聚酯玻纤布和玻纤格栅防反效果较差；通过镀锌铁网和H型功能材料研发的DGQ防反性能和抗锈蚀性能十分显著，可做到常温施工，性价比高，具有良好的推广应用 前景。
