摘要
结合我国部分高速公路的路面结构情况,分析得出了最优的路面结构组合和厚度,并对沥青路面不均匀沉降进行了应力分析,提出了减轻城市道路结合处路面损害的措施。建立了沥青路面沉降的有限元法计算模型并利用数值软件进行分析,可为沥青路面结构的设计和施工提供参考。
Combining with the status of pavement structures of some expressway in China, the optimal pavement structure and depth of pavement is concluded. Through the analysis of the stress in allusion to the uneven settlement of asphalt pavement, the measures for reducing the damage of the urban road junctions are put forward. The finite element model for asphalt pavement settlement calculation is established, and it is analyzed by numerical software, which provides references for the design and construction of asphalt pavement structure.
