摘要
SBS作为一种热塑性弹性体 ,是苯乙烯—丁二烯的嵌段共聚物 .通过在国产 10 0 #石油沥青中添加不同剂量的SBS进行改性 ,研究其对石油沥青各项性能指标的影响 ,同时和参考标准进行对比来评价其改性的效果 .结果表明 ,石油沥青中添加 4 %SBS可以明显改善石油沥青的高温稳定性、低温抗裂性和感温性 。
Styrene-Butudience-Styrene(SBS) is a kind of thermo-plastic elasticity.This paper stadies the effect of modified agent on modified asphalt performance by adding various percentage SBS.At the same time,by referring to the standards,the modified effect is evaluated. It is found that modified asphalt added 4 percent SBS is able to improve high-temperature stability,low-temperature anti-cracking performance and high-temperature susceptility of petroleum asphalt,which is enough to satisfy the performance standards.
