摘 要: | 采用SBS和EVA对路用煤-石油基混合沥青进行改性处理,对SBS和EVA引起的炭沥青改性效果进行了研究。结果表明,SBS改性后的炭沥青具有更好的高温抗丰辙、低温抗裂性能和感温性能,采用4.5%~6%的SBS改性炭沥青(软化煤沥青比例为15%),所得性能最优。

Abstract: | The modification of carbobitumen by SBS and EVA was compared, and the results show that SBS-modified carbobitumen has better high-temperature rutting resistance, low-temperature crack resistance and temperature susceptibility performance than EVA-modified carbotumen. It is also found that carbobitumen with 15% softening coal tar pitch modified by 4.5%- 6% SBS has the best performance. |
