摘要
为判别沥青稳定碎石基层级配组成与高温稳定性之间的联系,采用骨架接触度SSC(stone-on-stone contact)来评价粗集料之间相互接触的密实程度,通过大量实验得出SSC与动稳定度之间的具体关系,为沥青稳定碎石基层配合比设计提供指导。
In order to decide the relationship between the asphalt stabilized crushed stone base gradation composition and the high-temperature stabilization,the stone-on-stone contract(SSC) is used to evaluate the mutual contact compaction rate among the coarse aggregates.The article puts forward the detail relationship between SSC and dynamic stabilization according to a large of experiments,which can be referred for the mixing ratio design of asphalt stabilized crushed stone base.
