高速公路改扩建工程路面结构及拼接设计研究

通过对郑漯和漯驻两条高速公路改扩建工程的旧路病害状况和病害成因的分析,提出了高速公路改扩建路面结构设计应考虑的因素,并明确了重载交通特征及量化指标;结合路面结构受力特征分析,推荐了高速公路改扩建合理的路面结构设计,并对改扩建路面衔接设计提出了建议和应考虑的关键因素。

Research on Pavement Structure and Splicing Design for Reconstruction and Extension of Expressway

Through analysis of old road disease condition cause of disease for reconstruction and extension of Zhengzhou-Luohe Expressway and Luohe-Zhuxin Expressway, factors to be considered in the pavement structure design for reconstruction and extension of expressway were put forward, and heavy-duty traffic characteristics and quantitative index were defined. Combined with the mechanics characteristic of pavement structure, the pavement structure design for reconstruction and extension of expressway was recommended, suggestions and key factors to be considered for reasonable pavement splicing design for reconstruction and extension of expressway were put forward.
