土工格栅对提高改建路面承载能力的研究

Study of Geogrid to Improve Bearing Capacity of Rebuilt Pavement

采用落锤式弯沉仪对试验路段基层底加土工格栅的右幅和未加土工格栅的左幅进行现场弯沉测试的结果分析表明,对于旧路改建路面,将土工格栅铺设在原路面上可以提高路面承载力,同时,利用格栅与基层材料的相互作用将荷载分散到更宽的承载面上,可提高路面的整体性、稳定性,这在旧路改建过程中是一个很好的延长路面使用年限的方法。

Adopting falling weight deflectometre survey between the geogrid right piece and non-geraise the bearing capacity by laying geogrid on original pavement and disperse on wider the area of bearing of the surface, which improved the whole and the stability of the pavement. So it is a very good method to lengthen the life of pavement by laying geogrid while the old road is rebuilded.
