• On the basis of the characteristics of high rigidity and excellent friction resistant, a new kind of steel slag SMA ( stone matrix asphalt ) concrete was designed and prepared. The main processes include aggregate gradation, performance analysis of steel slag before and after aging, preparation methods and properties test of steel slag SMA . The experimental results indicate that the index of steel slag' s activation is less than 1 petting, the dynamic stability is 5699 times/mm, and both the residual stability and ratio of frozen splitting strength are more than 80 percent ; the friction factor and structure depth are 67. 1%b and 0.7 mm respectively. These nmdts show the steel slag SMA is superior to the common asphalt concrete and SMA that uses common aggregate.
