摘要
采用YH-791、YH-792和道改2#三种SBS改性剂对镇海AH-70沥青进行改性,对三种SBS改性沥青的针入度、延度、软化点、针入度指数PI、当量软化点、当量脆点、弹性恢复等主要技术性能进行了试验和比较分析.并将SBS含量为5%的三种SBS改性沥青的主要技术性能指标与现行规范的指标进行了比较,为SBS改性沥青生产中改性剂品种的选择及改性沥青的生产质量控制提供依据.
The original asphalt of Zhenhai AH-70 is modified with YH-791, YH-792 and Daogai-2# three species of SBS modifier, the penetration, ductility, softening point, penetration index（PI）, equivalent softening point, equivalent brittle point, recovery of elasticity and so on of the basic technical performance indicators of the three species of SBS modified asphalt are proceed experimentation and comparative analysis. And compared the basic technical performance indicators of the three SBS modified asphalt whose content is 5% with the indices of the technical specifications, those can supply reference to the modifier selected in SBS modified asphalt and the quality controlled of modified asphalt.
