废胶粉改性沥青研究进展

Research Progress on Crumb Rubber Modified Asphalt

介绍了废胶粉改性沥青的国内外研究和应用现状,分析了胶粉改性沥青的特点、改性机理及制备方法等。指出废胶粉用于改性沥青,既能提高沥青的性能,降低产品成本,又能促进废旧橡胶的循环利用,减少环境污染,具有显著的环保效益和明显的经济社会效益。

The present of research and application on crumb rubber modified asphalt at home and abroad was introduced. The characteristic, mechanism, preparation method of the crumb rubber modified asphalt were analyzed. It was pointed out that the application of crumb rubber in asphalt modification could not only improve the performances of bitumen and reduce the cost of production, but also promoted the reuse of used rubber and decrease environment pollution as well. So it was of great value in environmental protection and economic benefit.
