【摘要】 通过浸水马歇尔试验、冻融劈裂试验、车辙试验和渗水试验来评价基于同种沥青不同级配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,分析了大空隙沥青混合料路用性能渗水性能与级配、空隙率的之间关系,从而为大空隙沥青混合料提供设计依据.更多还原

【Abstract】 According to immerseable Marshall test,frost thawing rail head test,rutting test and permeable test,the evaluation is got by water-stability,temperature-stability and permeable performance of OGFC based on same asphalt different gradation,and the relationship between permeable performance and gradation or air void of OGFC is analysed.Therefore,the design standards are provided for OGFC.更多还原
