橡胶改性剂与SBS复合改性制备高黏度改性沥青的研究

Preparation of High Viscosity Modified Asphalt with Rubber Modifier and SBS

采用了SBS与橡胶改性剂复合改性制备高黏度改性沥青,研究了不同橡胶改性剂掺量制备改性沥青的性能,并研究了高黏度改性沥青排水沥青路面混合料的性能。结果表明:SBS与橡胶改性剂复合改性能够制备适合排水沥青路面的高黏度改性沥青,并得出了6%与8%是橡胶改性剂合适的添加掺量,研究出了适合排水沥青路面的高黏度改性沥青配方。

UsingSBS and the rubber modifier as a compound modifier to produce high viscosity modified asphalt,the performance of asphalt in different amounts of rubber modifiers was studied.The high viscosity modified asphalt drainage asphalt mixture performance was studied as well.The results show the rubber and SBS compound modifier can produce high viscosity modified asphalt which is suitable for drainage asphalt pavements.It shows that 6%and 8%rubber modifier was the appropriate ratio for the compound.Based on the result,a high viscosity modified asphalt composition for drainage asphalt pavements is developed.
