Study on Performance of AC-16 Asphalt Mixture with Different Steel Slag Content
The feasibility of applying steel slag to road construction and the performance characteristics of steel slag asphalt mixture are studied,and the variation law of mixture performance with different steel slag content is revealed.Steel slag asphalt mixture was prepared by substituting 0％,25％,50％and 75％steel slag for limestone aggregate.High temperature uniaxial penetration test,low temperature cleavage strength test,freeze-thaw cleavage strength test and indirect tensile fatigue test were used to study the high temperature performance,low temperature performance,water stability and fatigue performance of asphalt mixture under different steel slag content.The test results show that all the performance indexes of steel slag meet the requirements of the specification,and can be used as aggregate to prepare asphalt mixture.After adding steel slag,the performance of asphalt mixture is improved to varying degrees.With the increase of steel slag content,various properties of asphalt mixture change differently.It is suggested that the steel slag content should be controlled at about 50％to achieve the best comprehensive performance of asphalt mixture.
