土工合成材料加铺层处治沥青路面反射裂缝效果对比研究

Comparative Study on Applying Geosynthetics Overlay to Treat Reflective Cracking on Asphalt Concrete Pavement

反射裂缝是半刚性基层上加铺沥青混凝土面层所要克服的主要病害。对反射裂缝的产生机理进行简要分析,并通过玻纤格栅与聚酯玻纤布的抗裂性对比试验,评价分析2类土工合成材料防治反射裂缝的性能。

Reflective cracking is a crucial disease to be overcome during applying asphalt concrete overlay on half rigid roadbed.This paper analyzes the forming system of reflective cracking,and through comparative experiments on anti-cracking property of both the fiber glass grid and polyester fiber-glass mat,last, it evaluates and analyzes the performance of prevention and treatment to reflective cracking by grade 2 geosynthetics.
