Research on Measured Temperature Field of Durable Asphalt Pavement in Wet and Hot Regions

介绍了新型耐久性长寿命路面结构设计方案,通过布设温度传感器对路面结构层内实测温度数据进行采集及分析,表明：路面结构层底温度随时间、深度均有较大变化,路面各结构层底温度随时刻变化存在不同幅度的波动性及热传递滞后性,面层温度在上升阶段和下降阶段均与气温存在较好的线性相关关系,相关系数达0.975~0.995。

In this paper, structure design of a new durable long life pavement has been introduced, with themeasured temperature data in the pavement structure layer being collected and analyzed by deployment of temper-ature sensors. The results have shown that the temperature of pavement structure bottom has great changes follow-ing time and depth, and along with the time change, the temperature of the bottom of each pavement structurelayer has different amplitude fluctuation and heat transfer hysteresis, and there is a good linear correlation be-tween the surface temperature and the atmospheric temperature in the rising and falling stage, the correlation co-efficient is up to 0. 975 -0. 995.
