影响长大纵坡沥青路面车辙的荷载因素分析

Influence of Load Factors on Rutting of Asphalt Pavement on Large Longitudinal Slope

为了找到影响长大纵坡沥青路面车辙的最不利荷载因素,从交通荷载的角度提出车辙防治措施,对坡度、车速和超载对长大纵坡路面车辙的影响进行了计算分析和比较。研究表明,坡度对长大纵坡的路面车辙的影响较小;与坡度相比,较低的车速更易导致车辙病害的产生;车辆超载是导致车辙产生和进一步恶化的最不利因素。

To find out the critical load factor leading to rutting on large longitudinal slope and control measures, this paper analyzes the influence of slope, speed of vehicle and overload on rutting on the asphalt pavement on large longitudinal slope. The result indicates that the slope has limited influence on the rutting. There is a direct correlation between speed of vehicle and rutting. The overload is proved to be the critical factor leading to excessive pavement rutting on large longitudinal slope.
