ABSTRACT
The paper presents the application potential of untreated/treated woven/non-woven coir geotextile in the unpaved roads. The chemical used for the treatment of the coir geotextiles were p-aminophenol, sodium periodate and sodium hydroxide. For this, laboratory monotonic load test was conducted in a test tank for the sand layer overlying clay and the untreated/treated coir geotextiles were placed at the interface under the unsoaked/soaked condition. The results of this study reveal that the models reinforced with untreated/treated woven and non-woven coir geotextiles show the improvement in the bearing capacity beyond a deformation of 9 to 13 mm. Further, models reinforced with untreated/treated woven and non-woven coir geotextiles show better improvement in the bearing capacity in the unsoaked condition in comparison to the soaked condition. Untreated/treated woven/non-woven coir geotextiles when placed at the interface of the sand layer overlying clay can be useful in unpaved roads in improving the bearing capacity especially in those situations where the rut depth is high as the improvement in the bearing capacity was realized up to larger deformation.
摘要
本文介绍了未经处理/处理的编织/无纺布椰壳纤维土工布在未铺筑道路上的应用潜力.用于椰壳纤维土工织物处理的化学物质是对氨基苯酚、高碘酸钠和氢氧化钠.为此，在试验箱中对覆盖粘土的砂层进行了实验室单调荷载试验，未经处理/处理的椰壳土工布在未浸水/浸泡条件下放置在界面处.本研究的结果表明，未经处理/处理的织物和无纺布椰壳纤维土工布加固的模型显示，变形超过9至13 mm后，承载力有所改善.此外，未经处理/处理的编织和无纺布椰壳纤维土工布加固的模型显示，与浸泡条件相比，未浸泡条件下的承载力有更好的改善.未经处理/处理的编织/无纺布椰壳土工布放置在覆盖粘土的砂层界面时，可用于未铺筑道路，以提高承载力，尤其是在车辙深度较高的情况下，因为承载力的提高可达到更大的变形.
