摘要
研究了不同废胶粉及其不同掺量对沥青的改性效果,认为胶粉添加量在18%～24%范围内,沥青性能改善明显;体系中添加配合剂时,性质会发生一系列的变化:软化点升高,低温柔性有所改善。
The effee.ts were investigated.The of crumb rubber on asphalt modification result shows that when crumb rubber added varies in the range of 18%-24% ,the properties of the asphalt are significantly improved.In addition,some additives can also play positive roles in asphalt modification,softening point increased and low temperature flexibility improved for instance.
