英文摘要	The phenomenon of low temperature cracking and freezing is easy to appear in the asphalt pavement of Gansu Province, which seriously affects the performance and safety of asphalt pavement in winter. The distribution law of the low temperature field of asphalt pavement was studied according to the weather data and the internal temperature of the pavement structure in Weiyuan area of Gansu Province. The cumulative and lag time of temperature and radiation that influence the asphalt pavement structure were determined by using statistical methods, and the correlation analysis of environmental factors that affected temperature field of asphalt pavement were carried out. The pavement temperature field prediction model suitable for Weiyuan area in winter was proposed based on the multi-factor stepwise regression analysis. The results show that the temperature of pavement structure change shows a decreasing trend with the increase of pavement depth. The influence of temperature and solar radiation on the temperature accumulation and lag of pavement structure is more and more obvious. The temperature model in the depth of pavement structure is improved when taking the time and depth as the error correction factor into the prediction model of asphalt pavement temperature field, which can accurately simulate the change of asphalt pavement temperature field in winter. © 2020, The Editorial Board of Journal of Basic Science and Engineering.
