伴随着经济社会的高速发展,由于经济发展的需要,未来很长一段时间的建设热点话题将成为高速公路的扩建,扩建后,大多数车道术将达到八车道。同时,高速公路车道的增加为车辆的管理模式的优化提供了条件,也为扩建工程路面设计实现原路充分利用、提高路面耐久性提供了条件。本文就原路四车道改扩建为整体八车道的高速公路路面设计进行探讨,提出分车道设计的相关理念,并针对相关参数的选择进行了研究。
With the rapid economic and social development, due to the needs of economic development, the hot topic of construction for a long time in the future will become the expansion of the expressway. After the expansion, most laneways will reach eight lanes. At the same time, the increase of expressway lanes has provided the conditions for the optimization of the vehicle management mode, and also provided the conditions for the full use of the original roads and the improvement of road durability in the expansion project pavement design. In this paper, the original four-lane reconstruction of the eight-lane highway pavement design to explore the proposed sub-lane design concepts, and for the selection of the relevant parameters were studied.
