矿料间隙率破坏的范数灰关联度分析

Norm gray association study of the voids in the mineral aggregate collapse

利用范数灰关联度方法,分析了影响矿料间隙率(VMA)破坏的因素.研究发现,级配、砂当量、拌合温度和集料形状等作用突出.结论对如何有效控制VMA,提高沥青混合料质量有实际意义.

With the norm gray relational grade analytical method,this paper analyses the factors that influence the VMA-voids in the mineral aggregate-collapse.It is discovered that aggregate gradation,FAA,plant production temperature and aggregate shape have great influences on the collapse.The conclusions are useful in effectively controlling VMA and enhancing the property of asphalt mixture.
