摘要	In order to establish a prediction model of high temperature field of asphalt pavement in Longnan area of Gansu Province, a typical section of Lanhai expressway located in Longnan area was chosen to collect the data of pavement structure at high temperature. The temperature data of pavement structure from actual measurements were used to analyze the changing regular of pavement temperature field in this area and the regression analysis method was adopted to analyze how temperature, solar radiation intensity, humidity and road depth would affect the temperature of road surface. The prediction model with temperature, humidity, solar radiation intensity and road depth as parameters was established. Research results show that as time goes on, the regular of temperature and humidity sinusoidal changes, and the influence of temperature and solar radiation intensity on pavement structure temperature is positively correlated. The effect of humidity on pavement structure temperature is negatively correlated. The influence of air temperature and solar radiation intensity on pavement structure temperature is accumulative and hysteresis. Through comparing the measured data collected in sites and the simulating data in three models, the high temperature field prediction model has a high correlation with the pavement structure temperature, which can simulate the high temperature field of Longnan asphalt pavement and provide technical support for the rut prevention and control of asphalt pavement in Longnan area. © 2018, Editorial Board of Journal of Huazhong University of Science and Technology.
