摘要
为促进聚合物改性沥青的发展,对橡胶类、树脂类及热塑性橡胶类3类常用聚合物改性剂进行调查,并对3个不同种类改性剂改性机理进行探讨。从常规指标、美国SHRP规范要求及新指标要求三方面研究聚合物改性沥青性能评价方法,并阐述了聚合物改性沥青技术的发展趋势。
In order to promote the development of polymer modified asphalt,the article describes the investments of three common polymer modifiers of rubber,resin and thermoplastic rubber,and discusses the modifying mechanisms of these three different modifiers.The article studies the evaluation methods of polymer modified asphalt performances from three aspects of the routine index,American SHRP standards and new index,and sets forth the development trend of polymer modified asphalt technology.
