Effect of Pavement Temperature Fluctuation on Mechanistic Behavior of Asphalt.

利用AMeDAS逐时气象观测数据，利用有限元方法对气温分布及其季节波动进行了理论计算。该程序是在MS Windows环境下开发的。根据建设部公共工程研究院开发的方程估算了国道实际沥青路面的车辙深度。该方程需要路面温度分布，这是使用我们的估计系统正确计算的。将结果与实际车辙深度进行比较，发现这两个深度几乎完全相同。然而，人们发现很难单独了解温度的影响，因为每个人行道的交通量和人行道结构都不同。

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.
