摘要
通过浸水马歇尔试验、冻融劈裂试验、车辙试验以及改进的渗水试验,来评价同一种级配不同沥青的大空隙沥青混合料的水稳定性、高温稳定性和渗水性能等,模拟在不同路面横坡度下大空隙沥青混合料的横向及竖向渗水系数与横坡度之间的关系,回归了路面横坡度与渗水系数之间的线性关系。
According to immerseable Marshall Test, Frost Thawing Rail Head Test,Rutting Test and Permeable Test, water-stability, temperature- stability and permeable performance of OGFC which is based on same gradation and different asphalt are evaluated, the relationship between transverse and vertical permeable coefficients of OGFC and transverse slop under different slope are simulated, and the linear relationship between permeable coefficient of OGFC and slope is regressed.
