| 摘 要： | The Xinjiang-Tibet Highway（XTH）is a transportation corridor of manpower and supplies from inland regions to Tibet. The XTH has the highest altitude in China，which also has complex geological conditions and high distress ratio. The pavement distress was investigated completely to analyze the spatial distribution of pavement distress along the XTH and reveal the relationship among different types of distress. The distress ratio of 7 types of pavement distress was obtained and the relationship of pavement distress and ground surface temperature，altitude and vegetation cover was quantitatively fitted along the XTH. The result shows that，distress occurrence ratio of racking is has the largest percentage，which is the main reason to reduce the road condition. Pavement distress has a positive correlation and interaction with each other. One type of distress appears with the formation and development of other types of distress. The pavement cracking of the roadway with high altitude was obviously influenced by solar radiation and freeze-thaw cycle，which has a larger occurrence scale and development ratio than other regions. This paper reveals the relationship of each pavement distress and environmental factors，and provides a scientific basis and theoretical reference for the operation，maintenance and distress treatment of the XTH and planning Xingjiang-Tibet transportation corridor. © 2022 Science Press (China).

| Abstract: | The Xinjiang-Tibet Highway （XTH） is a transportation corridor of manpower and supplies from inland regions to Tibet. The XTH has the highest altitude in China， which also has complex geological conditions and high distress ratio. The pavement distress was investigated completely to analyze the spatial distribution of pavement distress along the XTH and reveal the relationship among different types of distress. The distress ratio of 7 types of pavement distress was obtained and the relationship of pavement distress and ground surface temperature， altitude and vegetation cover was quantitatively fitted along the XTH. The result shows that， distress occurrence ratio of racking is has the largest percentage， which is the main reason to reduce the road condition. Pavement distress has a positive correlation and interaction with each other. One type of distress appears with the formation and development of other types of distress. The pavement cracking of the roadway with high altitude was obviously influenced by solar radiation and freeze-thaw cycle， which has a larger occurrence scale and development ratio than other regions. This paper reveals the relationship of each pavement distress and environmental factors， and provides a scientific basis and theoretical reference for the operation， maintenance and distress treatment of the XTH and planning Xingjiang-Tibet transportation corridor. |
