摘要
该文通过CBR实验和粗集料填充密度实验,确定粗集料各粒径在最强和最密实状态下的比例,并引入骨架因子和密实因子对粗集料骨架进行优化,从而设计出强度高、密实性好的粗集料,为骨架密实型沥青混合料的实现提供支撑。
The article defines the proportion of each granule of coarse aggregates at the strongest and the densest status through CBR experiment and coarse aggregate filling density,and introduces the framework factor and density factor to optimize the coarse aggregate framework so as to design the high intensity and good density of coarse aggregate for providing the support to realize the density-framework asphalt mixture.
