上海市柔性基层沥青路面典型结构设计初探

Initial Discussion on Typical Structure Design of Flexible Base Asphalt Pavements in Shanghai

近年来,出于加快施工进度的考虑,上海市政系统在很多公路大中修或道路改建工程中,采用了柔性基层的沥青路面结构。由于缺乏深入的研究,各家设计单位设计的此类路面结构组合不尽统一。为此,在分析研究柔性基层沥青路面结构设计现状的基础上,通过统一设计参数和材料参数的选取,经过软件计算,给出上海市柔性基层沥青路面典型结构组合,以方便设计人员选用,并对使用柔性基层提出了想法和建议。

In recent years, to speed up the schedule of construction, the flexible base asphalt pavement structure is used in many municipal highway overhaul or municipal road reconstruction projects of Shanghai.Owing to no further study, this kind of pavement structural composition designed by the design unites is not unified. Therefore, on the basis of analyzing and studying the design situation flexible base asphalt pavement structure, and according to the selection of the unified design parameters and material parameters, the typical structural composition of flexible base asphalt pavement for Shanghai is achieved by the software calculation easily for the designers to choose. And the ideas and suggestions are proposed for the use of flexible base.
