摘要
本文简要讨论了国内外所用的沥青改性剂及改性沥青混合料的主要使用性能,并介绍了在华北地区用SBS和SBR改性沥青铺筑的不同试验路的实际使用性能.橡胶沥青的初期效果明显.SAM作为旧沥青面层的养护措施和新面层上的橡胶沥青表面处治都有明显效果.
The paper discusses briefly the main performances of modified bitumen and its mixes used at home and abroad. The performances of various trials using SBS and SBR modified bitumens in North China are presented. The effect of rubberized bitumen is clear in early period. The effects of SAM used on old bituminous pavement as maintenance measure and the rubberized bitumen surface dressing on newly constructed bituminous pavement are obvious.
