摘要
介绍了玻纤格栅、土工布在沥青加铺层改造旧水泥混凝土路面中的应用实例 ,进行了理论分析、疲劳试验。结果表明 ,采用土工合成材料可有效地减少由荷载、温度、地基脱空等产生的不利影响 ,延缓原有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 。
Some newly developed synthetic materials are used in the civil engineering to strengthen the earth structures.They are the glass geogrid and the geotextile.It is good at its higher tensile strength,higher elasticity,and better consistent with hot mix asphalt.An engineering example of the application to the asphalt overlay is introduced in the paper.The theoretical analysis and fatigue test are conducted in the study.The results show that the unfavorable effects caused by load,temperature,foundation and others can be lightened by the geosynthetics.It can also retard the reflection creaking, reduce the thickness of asphalt overlay and have a lowcast.
