高黏沥青混合料 SMA-10 性能研究

Study of Properties of SMA-10 High-viscosity Asphalt Mixture

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。

Abstract:

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.
