反应型活性橡胶添加剂对改性沥青胶结料性能的影响研究

Research on Impact of Reactive Rubber Additives on Properties of Modified Asphalt Binders

基于室内试验,研究添加剂掺量对SBS改性胶结料性能指标影响规律,进一步验证反应型活性橡胶添加剂加入沥青胶结料后对相关性能的作用机理。研究结果表明:随着反应型活性橡胶添加剂掺量增加,沥青胶结料的高温性能、抗车辙性能得到较大程度提高,抗变形能力优于原样SBS改性沥青。

In this paper,based on reactive rubber indoor tests,the effects of different dosage of rubber additives on the index of SBS modified binder were studied respectively and the mechanism of action of adding reactive rubber additives to asphalt binder was further verified.The results showed that with the increase of reactive rubber additive amount,the high temperature performance and anti-rutting resistance of asphalt binder were improved to a greater extent,and the anti-deformation ability was better than that of original SBS modified asphalt.The results provide some references for the application of reactive rubber additives.
