摘要
文章结合工程实例,分析SBS改性剂含量的增加对沥青针入度、延度和软化点三大指标的影响,阐述了SBS改性沥青设计、制备与施工要点,并通过试验验证了SBS改性沥青在高速公路工程中的运用效果。
Combining the engineering examples, this article analyzed the influence of SBS modifier content increase on three indexes of penetration degree, ductility and softening point of asphalt, described the main points for the design, preparation and construction of SBS modified asphalt, and veri- fied the application effect of SBS modified asphalt in expressway engineering through experiments.
