| 摘 要： | 采用双圆垂直均布荷载模式,利用Shell设计法对带残留层的冷再生基层沥青路面结构力学响应进行分析.结果表明残留层模量、厚度直接影响再生层与残留层层底拉应力,高模量薄厚度的残留层对再生层设计是不利的.在有残留层存在时,冷再生基层沥青路面设计应考虑残留层的厚度和模量.

| Abstract: | Structural mechanics response of cold recycling base asphalt pavement with residual layer is analyzed with Shell design method by model of double circular vertical uniformly distributed load.The results show that modulus and thickness of residual layer directly influence the bottom tensile stress of recycling layer and residual layer.High modulus and small thickness of residual layer is bad for recycling layer design.The design of cold recycling base asphalt pavement should take thickness and modulus of res... |
