摘要
通过研究冷再生结构层受力分析,在室内试验数据基础上,采用有限元BISAR软件对冷再生结构层以及常规半刚性路面结构层进行力学响应分析,得出了常规半刚性基层与冷再生基层力学响应的差异、冷再生层合理厚度、冷再生基层路面铣刨深度以及冷再生基层路面的使用条件.该研究对冷再生结构层设计与施工具有一定的借鉴作用.
The stress response analysis was conducted on cold recycling structure layer and the conventional semirigid structure layer with finite element software BISAR based on laboratory test data. The stress response difference of conventional semi-rigid base course and cold recycling base course, the sound thickness of the cold recycling layer, the milling depth and service condition of the cold recycling base course pavement were obtained. The study may give references for the design and construction of the cold recycling structure layer.
