摘要
采用低温延度、当量脆点和弹性恢复等指标对SBS1301-1,SBS4303-2改性沥青的低温性能进行了研究,研究结果表明:掺入SBS改性剂,可提高沥青的低温性能,并得出这两种改性沥青最佳掺量均为4%的结论。
This paper researched the low temperature performance of SBS1301-1, SBS4303-2 modified asphalt using low temperature ductility, e- quivalent brittle point and elastic recovery and other indexes, the results showed that, incorporation of SBS modifier could improve the low tem- perature performance of asphalt, and gained that the conclusion of the optimum content was 4% of this two kinds of modified asphalt.
