摘　　要：冷拌超薄罩面沥青混合料油石比及最佳级配的确定有利于指导路面养护施工。选用SMA-10、Novachip Type B与UTAC-10三种级配,应用标准马歇尔试验,能够测出三种级配的稳定度、饱和度和空隙率等指标,确定冷拌超薄罩面沥青混合料最佳级配;应用修正马歇尔方法,能够得到三种级配的沥青混合料最佳油石比。In order to determine the best gradation and asphalt aggregate ratio of cold mix ultra-thin overlay asphalt mixture and better guide the construction, the stability, porosity and saturation of SMA-10, Novachip Type B and UTAC-10 are measured by standard Marshall experiment to determine the best gradation of cold mix ultra-thin overlay asphalt mixture. The modified Marshall method is used to determine the optimum asphalt aggregate ratio of SMA-10, Novachip Type B and UTAC-10.
