Comparison of the Impact of Rubber Modified Asphalt and SBS Modified Asphalt of Steel Slag Asphalt Mixture
In this study,by comparing the performance differences between rubber modified asphalt and traditional SBS modified asphalt as the cementing material of steel slag asphalt mixture,the influence of differ-ent modified asphalt on the road performance of steel slag asphalt mixture was analyzed.The asphalt basic per-formance test,rutting test,Marshall test,freeze-thaw splitting test,Kentaburg immersion dispersion test,low temperature bending test and volume stability test were used to comprehensively evaluate the performance of two modified asphalt steel slag mixtures.The results show that the rubber modified asphalt steel slag mixture has a significant improvement in low temperature crack resistance,high temperature stability,water stability and volume stability compared with the traditional SBS modified asphalt mixture,and reduces the amount of asphalt.At the same time,rubber modified asphalt mixture also shows a positive effect in improving the fa-tigue life of steel slag pavement.These results expand new ideas for the application of steel slag asphalt mix-ture in road engineering,and are expected to provide a theoretical reference for enhancing the durability and overall performance of the road.
