the results show that percent air voids and percent of voids filled with asphalt in asphalt mixtures have great influence affect k value which indicates the extension of fatigue life.
研究表明:混合料饱和度和空隙率对k值,即沥青混合料疲劳寿命有较大影响;
according to the permeability plots of typical mixture, presents the control standard of percent air voids for request of permeability.
进而针对典型的沥青混合料,提出基于满足渗水要求的临界空隙率控制标準。
the base has bigger percent air voids and can promptly detain pavement interior water, and can effectively reduce the reflection crack.
这种基层具有较大的空隙率,能及时排走滞留在路面内部的水分,并能有效地减少反射裂缝的发生。
the results show that the vma value computed by percent air voids in bituminous mixture plus percent total bitumen volume in bituminous mixtures is bigger than the vma value by america method.
研究表明:我国的计算方法之一,用空隙率与总沥青用量的和计算的vma明显偏大,有时难以排除不满足最小vma要求的混合料。
