摘要
针对东北地区高速公路沥青路面状况,依据东北地区道路冻区、交通等级、土基强度等级,采用有限元对路面结构应力、应变及弯沉等指标进行了力学分析,提出了不同冻区、不同干湿类型、不同土质和不同冻深条件下抗冻垫层厚度设计方法及推荐值,最后给出东北地区高速公路沥青路面典型结构。
In this paper, according to asphalt pavement condition of northeast freeway, based on the traffic level and subgrade strength grade on northeast cold areas, the author analyses the indicators of pavement structure stress, deformation and deflection, proposes the design method and the recommended value of frost cushion thickness in different cold areas, different dry and wet zones, different frozen depth and soil conditions, and finally proposes the typical northeast asphalt pavement structure of northeast freeway.
