高速公路使用状况评价与养护维修方案设计

The Pavement Evaluation and Maintenance Scheme Design of Expressway

根据沪渝高速公路G50江北至长寿段路面大修工程,从交通量调查与原有路面结构分析入手,进一步评价了该路段使用性能以及病害产生的原因,在此基础上对沥青混凝土路面使用状况进行评价,针对病害的特性,结合工程实际情况,对不同的项目类型和路段提出加铺、罩面、翻修等不同处治方案,可为类似工程提供参考。

This study took Changshou district from Shanghai the pavement major repair works of expressway - GSO sections of Jiang - bei to to Chongqing as an example to investigate the volume of traffic and the original pavement structure, and then evaluated the performance and the causes of diseases. We evaluated the situation of asphalt concrete pavement after fully recognize the pavement performance and diseases. We directed the characteristics of the disease, combined with the actual project situation, finally put forward additionally paved, overlay, renovation scheme projects for different project types and sections, such targeted scheme design concept can provide a reference for similar projects.
