摘要
玻纤格栅作为近年来开发的新型土工合成材料,因其有较强的抗拉强度、较高的弹性模量和与沥青混凝土较好的相容性等特点,已逐渐应用于道路工程中。本文介绍了玻纤格栅应用于沥青加铺层改造旧水泥混凝土路面的实例,并对其进行了理论分析。结果表明,采用土工合成材料可有效地延缓原水泥混凝土路面的接、裂缝在沥青混凝土加铺层中的反射,减少加铺层厚度,还可节省工程造价。
Glass fiber geogrid as newly developed synthetic materials are gradually used in the highway engineering because of its harder tensile strength, higher elasticity and better compatibility with HMA. This paper introduces an engineering example of application of glass geogrid and geotextile in asphalt overlay. The application research includes the theoretical analysis and fatigue test. The results show the geosyntheties can effectively delay reflection creaking, reduce the thickness of overlay, and construction costs.
