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。 Marsh water test, freeze-thaw splitting test, rutting test and improved water seepage test were used to evaluate the water stability, high temperature stability and water seepage performance of the large void asphalt mixture with the same gradation and different asphalt. The relationship between horizontal and vertical water seepage coefficient and horizontal gradient of large void asphalt mixture under horizontal gradient regresses the linear relationship between the horizontal gradient of slope and water seepage coefficient.
