Abstract: Taking the structure of asphalt concrete pavement in actual running as the test object, a kind of actual measurement project for temperature field pavement structure was put forward. Based on the abundant measured temperature data, distribution rules of asphalt pavement temperature field were studied in detail, and the dependency relations between the air temperature and pavement temperature field were discussed with regression analysis. Considering the effect difference to asphalt pavement temperature field which was applied by temperature rise period and temperature fall period of air, the dependency relations between air temperature and different temperature changing periods were researched respectively and the prediction models on asphalt pavement temperature based on different temperature changing periods were established. The comparison between measured and predicted asphalt pavement temperatures indicates that these models have good applicability and accuracy.
