摘要
利用CBR试验研究了沥青混合料最强骨架时粗集料的级配,结合VCA均匀设计的研究成果,提出最强骨架与最密实骨架的均衡系数以及沥青混合料骨架优化设计。
It＇s made to utilize CBR test to study what is the gradation of coarse aggregate as the asphalt mixture is one having the strongest skeleton. In the light of fruits researching the VCA homogeneous design, the paper poses the equalizing coefficient between the strongest skeleton and the densest one as well as the optimization design of asphalt mixture＇s skeleton.
