Abstract: The flexure-tension resistant performance and flexural fatigue life of semi-rigid roadbase cement stablilized crushed stone medium beam is investigated experimentally in this paper. The influence on the stress?deformation and fatigue is comprehensively analyzed while soil engineering grid is laid at the bottom of semi-rigid base material .The results show that the Flexure-tension resistant performance and fatigue life is much more nicer than that of common semi-rigid base material

Key words: road engineering, soil engineering grid, semi-rigid roadbase material, flexure-tension resistant performance, Flexural fatigue life

摘要: 本文对铺设土工格栅与未铺设土工格栅的公路路面半刚性基层材料水泥稳定碎石中梁试件进行抗弯拉和弯 曲疲劳试验研究,分析T:i:T格栅位于半刚性基层材料底面时对材料受力、变形及疲劳寿命的影响。结果表明,铺 设土工格栅的半刚性基层材料的抗弯拉性能和疲劳寿命明显高于普通的半刚性基层材料。
