| 摘 要： | 通过对聚酯长丝土工布和玻纤格栅两种土工合成材料的试验,说明在受力条件下,土工布和沥青混凝土基本是同步变形,可以共同起作用。所以土工布不仅仅是隔离,也起到加筋的作用。再经薄面强基+土工合成材料结构模式的可行性分析和实践,说明在防治反射裂缝作用方面,土工布比玻纤格栅的效果会更好一些。

| Abstract: | Tests of two geosynthetics, polyester geotextile and fiberglass geotechnical grid, show that geotextile under stress can keep step with asphalt concrete in shaping. So, geotextile can act not only for isolation but for reinforcement as well. It also demonstrates, through the feasibility analysis and practice of the structural mode of whittling down the surface and strengthening the foundation plus geosynthetic, that geotextile is better than fiberglass geotechnical grid in prevention from reflection cracks. |
