ZIGLER岩沥青改性沥青混合料的性能研究

Research on Performance of ZIGLER Gilsonite Modified Asphalt Mixtures

岩沥青常被用作为沥青路面的添加剂,已在国内外一些工程中得到应用。本研究用韩国SK基质沥青和台湾CPC基质沥青分别对不同掺量岩沥青胶结料性能进行了比较分析。采用AC-25沥青混合料,基质沥青为韩国SK-70号沥青,分别对不同掺量岩沥青改性沥青混合料性能进行了比较分析,推荐了岩沥青的适宜掺量。

Gilsonite is often used as an additive of asphalt pavements. It has been applied in projects of China and other countries. Performances of gilsonite asphalt binder are compared and analysed when different contents of gilsonite are blended into Korea SK asphalt and Taiwan CPC asphalt. Performances of gilsonite modified asphalt mixtures are compared and analysed when different contents of gilsonite are blended into AC-25 asphalt mixtures and Korea SK 70 # used as basis asphalt. The appropriate contents of gilsonite are recommened.
