吐乌大高速公路路面扩建设计分析

Pavement Extension Design of Turpan-Urumqi-Dahuangshan Expressway

结合国内路面改扩建工程实践,针对吐乌大高速公路现有路面状况、强度及路面结构形式,分析现有路面病害产生的原因,依据改扩建完成后车辆分布特点,提出分车道路面设计原则。结合新疆特有的地形、地貌、气候、水文等特点以及对现有路面病害处理对策,进行路面结构设计,为其他项目路面改扩建提供参考。

Combining with the practice of pavement extension engineering in China, in allusion to the current situation, strength and structural mode of the pavement of Turpan-Urumqi-Dahuangshan Expressway, the paper analyzes the causes of pavement diseases, and proposes the divided lane pavement design principle according to the vehicles＇ distribution characteristics since extension engineering is finished. The pavement structure is designed in view of the proper landform, physiognomy, climate, hydrology and other characteristics of Xinjiang as well as the current countermeasures of pavement diseases, which can provide references to similar projects.
