摘要
以辽河石化90#道路石油沥青为载体,试验分析了不同掺量条件下的硫化橡胶粉改性沥青软化点、针入度、延度、老化性能以及流变性能,对比SBS改性沥青性能分析了橡胶粉掺量对沥青胶浆高温、低温、抗老化性能、弹性恢复性能方面的改善作用。
This paper analyzes the softening point, needle penetration, ductility, aging quality and rheological proper- ties of rubber modified asphalt in different dosage, based on petroleum asphalt of Liaohe Petro Chemical 90#. Compared with the function of the SBS modified asphalt, a study in the improving function of the rubber powder content in high-temperature behavior, low temperature behavior anti-fatigue behavior, and elasticity recovery capacity is also made.
