SBS改性沥青常规指标与SHRP性能指标的关系

The relationship between the conventional index and SHRP performance index of SBS modified bitumen

笔者选取了具有代表性的4种国产重交通道路石油沥青和4种专用型道路沥青改性剂,在试验室里采用高剪切的改性工艺制备得到16种SBS改性沥青;运用常规试验方法和SHRP试验方法,对制备得到的SBS改性沥青的高低温性能进行了研究;在综合分析各种沥青的试验结果的基础上,提出了常规高低温指标与SHRP高低温性能指标之间的关系.

With four types of representative domestic road bitumen used to highway traffic and four types of specified road bitumen modifiers, sixteen SBS modified bitumens were prepared through high-shear modifying technique in the laboratory. The high - low temperature performance of SBS modified bitumens were characterized using conventional methods and SHRP test methods,Based on analyses of test result, This paper demonstrates the relationship between the conventional index and SHRP perfomance index of SBS modified bitumen.
