中文摘要：

为更好地协调排水沥青混合料的耐久性与排水性之间的矛盾,把粗骨料空隙填充法（CAVF）设计方法引入到排水沥青混合料的组成设计当中,用毛体积相对密度作为衡量压实效果的指标,以压实试件达到最大毛体积相对密度时的温度作为最佳压实温度,在此温度下成型排水沥青混合料试件,并对其水稳定性、高温稳定性、渗水性与抗滑性能进行检验。试验结果表明：以压实试件达到最大毛体积相对密度时的温度作为最佳压实温度是合理的,设计的排水沥青混合料的水稳定性、高温稳定性、渗水性与抗滑性能均远远超过规范要求,即使在70℃的高温条件下也能表现出良好的稳定性,证明了采用CAVF设计方法设计骨架嵌挤结构沥青混合料的优越性。

英文摘要：

In order to harmonize the conflict between durability and drainability of porous asphalt mixture better,course aggregate void filling（ CAVF） method is introduced into the mix design of porous asphalt mixture,the bulk volume relative density is taken as a measure to evaluate compacting effect,and the temperature which when the compacting specimen reaches the maximum bulk volume relative density is chosen as the optimum compacting temperature,at which the porous asphalt mixture specimen is modeled,and its properties such as water stability,high temperature stability,permeability and skid resistance are tested. The test result shows that（ 1） it is reasonable to take the temperature which when the compacting specimen reaches the maximum bulk volume relative density as the optimum compacting temperature;（ 2）water stability,high temperature stability,permeability and skid resistance of the designed porous asphalt mixture far outweigh the specification requirements,and it shows good stability even at the high temperature of 70 ℃,which proves that the CAVF method has advantages to design the asphalt mixture with skeleton intedocking structure.
