摘要
通过多种性能评价方法,考察了SBR剂量以及添加稳定剂对SBR/SBS改性沥青性能的影响。试验结果表明,SBR剂量超过4%导致沥青离析。加入稳定剂使聚合物产生交联,导致SBR/SBS改性沥青的延度降低、粘韧性和抗变形能力提高。
Different kinds of evaluation methods stabilizer to the performance of SBR/SBS modified asphalt. Investigations have shown that more that 4% of SBR to resulted eduction. The addition of stabilitor caused chemical crosslink and formed elastic network structure in the asphalt,which led to reduce ductility and improvement of visco-toughness and resistance to deformation.
