Abstract：High-viscosity rubber-modified asphalt was prepared using a self-developed SBS/rubber composite modifier,and compared with matrix asphalt,TPS modified asphalt,and XC modified asphalt.The test results show that compared to base asphalt mixtures,the dynamic stability,flexural strength,maximum bending tensile strain,freeze-thaw splitting strength ratio,and residual stability of the self-developed high-viscosity asphalt mixtures SMA-13 and OGFC-13 increased by 5.25 times and 5.87 times,32.9%and 116.4%,29.8%and 36.7%,15.5%and 19.5%,and 10.01 and 11.82 percent points,respectively,indicating that high-temperature performance,low-temperature performance and water stability are all good,and superior to TPS and XC modified as-phalt mixtures.The noise reduction performance of the self-developed high-viscosity asphalt mixture is also superior.When the surface of the mixture has a lower surface exposure rate and deeper surface structure,it can effectively enhance the noise reduc-tion performance of asphalt mixtures.
