高速公路扩建车道数的增加,为实现车辆分车道运行管理提供了条件,为实现充分利用原路与提高路面耐久性的路面设计理念提供了前提.针对沪宁高速公路江苏段原路4车道改扩建为整体8车道的高速公路进行了分车道路面设计,并通过对改扩建后道路实际运行状态的统计分析,就相关设计技术参数的选择进行了验证.验证结果表明多车道高速公路路面分车道设计是经济、可行、合理的,且具有推广价值.
The increase of the number of expressway lanes has provided the conditions for vehicle lane management and provided the preconditions for realizing the pavement design concept of full utilization of original roads and improving the durability of pavement.For the reconstruction and extension of 4 lane lanes of the section of Shanghai-Nanjing Expressway The design of sub-lanes for the whole eight-lane expressway was carried out and the selection of the relevant design parameters was verified through the statistical analysis of the actual operation state of the road after the expansion and expansion.The results of the verification showed that the sub-lane design of multi-lane expressway It is economical, feasible and reasonable, and has the promotion value.
