摘要
传统的聚合物改性沥青中沥青与聚合物之间没有发生明显的化学反应,只是物理改性。而沥青—聚合物反应性共混改性使沥青与聚合物在共混过程中发生交联、接枝等化学反应,从而改善改性沥青的相容性并提高改性沥青路用性能。阐述了沥青—聚合物反应性共混改性技术的研究现状,并对反应性共混改性技术的原理及各种方法进行了评述。
The chemical reactions didnt take place between polymer and asphalt in polymer modified asphalt prepared by the traditional modification processes, while by the reactive modification processes some chemical reactions such as cross-linking reactions and grafting reactions occured between asphalt and SBS. The compatibility and performances of reactive polymer-asphalt blends were improved. In this article, the present research of asphalt-polymer reactive modification was systematic elaborated and the mechanism and methods were remarked.
