拉日高等级公路沥青路面结构设计研究

Research on Asphalt Pavement Structural Design of Lhasa-Shigatse High-grade Highway

设计合理的高等级公路路面结构,选择合适的材料是确保沥青路面具有较好的路用性能的重要环节。为了探究拉日高等级公路路面结构设计思路,结合属地化设计特征及以往经验,研究西藏地区路面结构设计的通用做法。

The design of high-grade highways of reasonable pavement structure and the selection of suitable materials are important part to ensure that asphalt pavement has better pavement performance. Combining with the localized design features and previous experience, the paper researches the common practice of pavement structural design in Tibet in order to explore the design ideas of pavement structure of Lhasa-Shigatse high-grade highway.
