摘　　要：在广泛的路面调查基础上,结合数值计算分析,提出了柔性结构、倒装结构、全厚式结构和复合结构等几种新型路面结构形式,并通过郎川公路改建工程试验路进行了验证,证明了高寒地区路面结构适应性设计采用柔性基层的有效性,并推荐了高寒地区沥青路面优选结构.Severe weather and weak environment have a significant influence on the long term performance of asphalt pavement structures in the Tibet Plateau and surrounding areas such as west Sichuan, north Yunnan and Qinghai Province. Current design specification based on the calibration of field investigation of pavement in inland areas is not sufficient to produce a sound pavement design. Based on computer simulation and comprehensive field investigation of asphalt pavements in the Tibet Plateau and surrounding provinces, several new types of asphalt pavement structures were proposed and a test road section was constructed and instrumented to monitor pavement performance. The research results show that flexible base layer should replace semi-rigid base layer to produce sound asphalt pavements with a long term performance, especially in cold regions.
