Effect of Pavement Temperature Fluctuation on Mechanistic Behavior of Asphalt.

利用AMEDAS的逐时气象资料，用有限元方法从理论上计算了温度分布及其季节变化。该程序是在MS Windows环境下开发的，根据建设部工务研究所开发的公式估算了实际国道沥青路面的裂缝深度。该方程需要路面温度分布，并使用我们的估计系统进行了适当的计算。将计算结果与实际车辙深度进行了对比，结果表明这两种深度基本一致。然而，由于每个路面的交通量和路面结构都不同，因此很难单独知道温度的影响。

Temperature distributions and their seasonal fluctuation were calculated theoretically by the hourly mete orological data of AMeDAS using the finite element method. The program was developed for MS Windows environment.Rut depths in actual asphalt pavements of national highways were estimated based on the equation developed in Public Works Research institute, Ministry of Construction. The equation requires pavement temperature distributions, which were properly calculated using our estimation system. The results were compared with the actual rut depth, showing that these two depths are almost identical one another. However, it was found to be difficult to know the effect of temperature alone, since the traffic volumes and pavement structures are different in each pavement.
