玻纤格栅在改造旧水泥混凝土路面中的应用研究

玻纤格栅作为近年来开发的新型土工合成材料,由于其具有较强的抗拉强度、较高的弹性模量和与沥青混凝土相容性好等特点,已逐渐应用于旧水泥混凝土路面改造工程中。本文对玻纤格栅增强路面混凝土结构强度、延缓和减少裂缝产生的机理进行了总结与分析。

Glass fiber geogrids as a newly developed geosynthetic materials has been gradually used in the old cement concrete pavement reconstruction project,thanks to its harder tensile strength,higher elasticity and better compatibility with HMA.This paper summarizes and analyzes the mechanism that glass fiber geogrid reduces and delays the cracks,strengthens concrete pavement structure.
