一种添加剂对沥青的改性研究

Study on Properties of the Asphalt Modified by an Additive

研究了一种添加剂对70#基质沥青和SBS改性沥青性能的影响。研究结果表明:添加剂对70#基质沥青的性能影响不大,对SBS改性沥青的性能提升作用显著。分别在SBS改性沥青中添加8%、9%、10%、11%和12%的添加剂,研究了添加剂在SBS改性沥青中的最佳掺量。研究结果表明:添加剂掺量为9%和10%时,改性沥青具有较好的综合性能。

The properties of 70#base asphalt and SBS modified asphalt with an additive were studied by experimental methods.The results show that the additive has little effect on the performance of 70#base as⁃phalt,and has a significant effect on the performance of SBS modified asphalt.Therefore,the additive is more suitable for modifying SBS modified asphalt.In order to study the best doping of additives in SBS modified as⁃phalt,8%,9%,10%,11%,and 12%additives were added to SBS modified asphalt.The results show that when the amount of additives is 9%and 10%,the SBS modified asphalt has good comprehensive perform⁃ance.
