1999年 4月江苏省汾水至灌云高速公路被确定为公路土工合成材料应用示范工程。为此专门成立了一个执行和研究班子 ,展开了对公路工程中土工合成材料应用技术的研究 ,并将土工合成材料主要用于路基加筋、过滤和排水、路基防护和路面裂缝防治等方面。
In April 1999, Fenshui-Guanyun Expressway in Jiangsu Province was identified as an application demonstration project of highway geosynthetics. For this purpose, a special executive and research team was set up to study the application of geosynthetics in highway engineering. The geosynthetics were mainly used in such aspects as roadbed reinforcement, filtration and drainage, roadbed protection and pavement crack prevention and control.
