摘　　要：采用实验室自主研发的高黏沥青,采用MARSHALL方法进行了SMA-10型混合料设计,通过一系列室内试验检测了混合料的高低温性能、水稳定性和耐盐蚀性,并与商品化SBS改性沥青制备的对比样进行了平行对比。结果表明:SMA-10高黏沥青混合料的高低温性能优于SBS沥青混合料,水稳定性和耐盐蚀性也具有明显优势。The SMA-10 high-viscosity asphalt mixture is designed by using the Marshall method and the high-viscosity asphalt developed independently in laboratory.The high-temperature and low-temperature properties,water stability and salt corrosion resistance of the mixture are detected through a series of laboratory test.The parallel comparison is carried out with the specimens prepared by the commercialized SBS modified asphalt.The result shows that the high-temperature and low-temperature properties of SMA-10 high-viscosity asphalt mixture are superior to SBS asphalt mixture,and its water stability and salt corrosion resistance have the obvious advantages.
