Abstract
This study prepared steel slag asphalt mixture by partially replacing basalt with recycled steel slag.The replacement rate for steel slag ranges from 15％to 55％.Meanwhile,the high-temperature stability,low-temperature crack resistance,water stability,and skid resistance of the mixture were analyzed.The research results indicate that steel slag can replace some basalt to meet the performance requirements of asphalt mixtures.With the increase of steel slag content,the high-temperature stability and skid resistance of the mixture gradually increase.The water stability and low-temperature crack resistance show a trend of increasing first and then decreasing.Based on the changes in various indicators,it is recommended that the optimal dosage of steel slag is 35％,and the high-temperature performance,low-temperature performance,and anti-skid performance should be improved by about 6.3％,16％and 14％,respectively.关键词
