Abstract：Based on test section of asphalt pavement in operation, a series of temperature sensors were buried and arranged for the long-term data collection and summary analysis of the temperature at different depth of the pavement structure, the correlation between atmospheric temperature and temperature of pavement surface was investigated, and the variation rule of temperature of asphalt pavement structure with the depth was also studied. It is found that with respect to the atmospheric temperature, the temperature change of pavement structure has an obvious hysteretic behavior, and they are remarkably correlated. In addition, the temperature of pavement structure has a good correlation with the change of pavement surface temperature, and with the influences of sunny day and rainy day conditions considered, a prediction model of pavement structure temperature was established with the pavement surface temperature, the depth of structural layer, time, etc., considered. It is shown that the calculation data of the model have a very good agreement with the measured temperature, and it can be applied to various asphalt pavement structures.
