摘要
Abstract
To analyze the effects of SBS modified asphalt and rubber modified asphalt on the road performance of steel slag asphalt mixture,comparative analysis of relevant performance was conducted using immersion Marshall test,rutting test,low-temperature bending test,and four point bending fatigue life test.The results showed that compared with using matrix asphalt,the immersion residual stability of SBS modified asphalt and rubber modified asphalt steel slag asphalt mixture increased by 9.3％and 12.5％respectively,the high-temperature dynamic stability increased by 20.1％and 30.0％respectively,and the low-temperature stiffness modulus increased by 15.2％and 20.7％respectively.The fatigue life at the same strain level was significantly improved.Comparison between SBS modified asphalt and rubber modified asphalt,rubber modified asphalt has a better effect on improving the comprehensive road performance of steel slag asphalt mixture,which can provide technical reference for engineering applications.关键词
