| 摘 要： | 采用其他聚合物替代部分，SBS（聚苯乙烯-聚丁二烯-聚苯乙烯嵌段共聚物）在不降低其综合性能的前提下，可以适当降低改性沥青的生产成本．采用SBS、SBS＋SBR（丁苯橡胶）和SBS＋LDPE（低密度聚乙烯）改性石油沥青，研究改性沥青的常规指标．试验结果表明，SBS＋SBR对沥青的高温抗车辙性能改善效果较好，对沥青低温性能的改善效果不及SBS．

| Abstract: | Polymers are used to replace part of SBS,can be appropriate to reduce the cost of production of modified asphalt.In this paper,SBS,SBS + SBR and SBS + LDPE were used to modify asphalt.the conventional indicators of it was studied.The experimental results showed that,asphalt with SBS + SBR modification had better high-temperature anti-rutting performance,but its low temperature performance was less than that modified by SBS.How to give full play to the mixed modifier of the advantages remains to be further s... |
