Abstract : To clarify the pavement service temperatures in different regions and to determine the test temperatures for pavement material , the highways under the jurisdiction of Hebei Transportation Investment Group were divided into four service temperature zones. COMSOL finite element software was employed to calculate the temperature fields of representative pavement structures in high , medium, and low-temperature seasons for each zone, and the material performance test temperatures for different layers in each service zone were determined. The results indicate that the pavement service temperatures in the high, medium, and low- temperature seasons are relatively higher in areas south of Baoding, with surface temperatures reaching up to 65 ℃ during the high-temperature season. The service conditions in areas north of Baoding are similar to those in high-cold zone, but the low- temperature service temperature in high-cold zone can drop to as low as -25 ℃ , which is 5 ℃ lower than in areas north of Baoding. Coastal regions exhibit the lowest high - temperature service temperatures, with a smaller difference between the extreme temperatures of the high and low-temperature seasons. The high-temperature performance test temperatures across the four service zones are relatively similar, while there are significant differences in the low - temperature performance test temperatures. The findings provide a reference for performance evaluation and structural design of materials in different temperature rangs.
