Based on the abundant measured temperature data, distribution rules of asphalt pavement temperature field w ere studied in detail, and the dependency relations betw een the air temperature and pavement temperature field w ere discussed w ith regression analysis.Considering the effect difference to asphalt pavement temperature field w hich w as applied by temperature rise period and temperature fall period of air, the dependency relations betw een air temperature and different temperature changing periods w ere researched respectively and the prediction models on asphalt pavement temperature based on different temperature changing periods w ere established. The comparison betw een measured and predicted asphalt pavement temperatures indicates that these models have good applicability and accuracy. Key words:road engineering;a
