| 摘 要： | 季节性冰冻地区公路沥青路面结构面临着较为极端的气候条件,因而,采用典型路面结构设计的方法成为现行国标的适当补充.本文分析了典型路面结构设计的必要性和客观性,并推荐半刚基层沥青路面及纯柔性沥青路面两种典型结构,采用现行设计方法验算了两种结构的设计指标的合理性.此外,采用壳牌沥青所推出的BISAR软件计算了弹性层状体系在静载下的荷载响应,对疲劳响应和静载响应进行了定量对比,从而力求使静载响应成为现行设计方法的有利补充.

| Abstract: | The extreme weather condition is one of the critical factors influencing highway with asphalt pavement in Seasonal frozen area. Typical pavement structure design is a reasonable method to deal with the special features, in this paper, a flexible asphalt pavement of semi rigid base asphalt pavement and a pure flexible asphalt pavement are recommended, they are checked with the current design method In addition, load response under static load is calculated using BISAR by Shell under the elastic layered system, and comparison between the fatigue response and static load response is carried out. Static load response can be s the beneficial supplement of the existing design method. |
