| Abstract: | On the basis of the characteristics of high rigidity and excellent friction resistance,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 percent,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% and 0.7mm respectively.These results show the steel slag SMA is superior to the common asphalt concrete and SMA that uses common aggregate. |
