摘要: 路面结构直接影响道路的使用性能,高海拔和低温气候是影响路面结构的关键因素。通过调查分析,归纳总结了西藏地区现有的路面结构类型;选取K2876~K3595段为典型路段并对路面 的病害类型进行了分析;以共玉高速为项目依托,采用四种新型路面结构进行试验路铺筑研究,并进行了温度场模拟。研究结果表明:柔性基层路面结构相对于半刚性基层路面结构在高寒地 区具有更好的适应性,其中土工格室加固级配碎石基层路面结构表现最优。

Abstract: The pavement structure directly affects the road performance,and the high altitude and the low temperature climate are the key factors to affect the pavement structure.The existing pavement structure types of Tibet area were summarized through the investigation and analysis.K2876~K3595 section was selected as a typical section and its pavement disease types were analyzed.Based on the “Gong-Yu Highway” project,the field research on the test road was carried out by adopting four new types of pavement structures;and the temperature field simulation was also carried out.The results of the study show that:compared with the semi-rigid base pavement structures,the flexible base pavement structures have better adaptability in high altitude cold area,among which the pavement structure with the reinforced and graded crushed stone base performs best.

Key words: road engineering, frozen soil area, pavement structure, adaptability analysis
