广东省公路路面典型结构分类标准研究

Study on Classification Standard of Pavement Typical Structure in Guangdong Province

重点从气候片区、交通荷载等级、路基等级、结构安全等级等四个方面对广东省公路路面典型结构的分类标准进行了分析和研究。研究系统地划分了广东省交通荷载等级、路基等级以及气候片区,提出适合广东省的公路路面典型结构分类标准,并将可靠度设计指标引入沥青路面典型结构设计中,明确量化了各级公路路面结构的安全性标准。其研究成果为研究广东省公路路面典型结构奠定了基础。

This paper has analyzed and studied emphatically the classification standard of pavement typical structure in Guangdong Province from the four aspects of the climatic region, traffic load grade, subgrade grade and structural safety grade. The study has systematically compartmentalized the traffic load grade, subgrade grade and climatic region of Guangdong Province, and proposed the classification standard of pavement typical structure suited to Guangdong Province, and introduced the reliability design index into the design of asphalt pavement typical structure, and clearly quarttiffed the reliability index of pavement structure of all levels highway. The research results will lay a foundation for studying the pavement typical structure in Guangdong Province.
