摘要
复合使用SBS和SBR改性剂,制成FH改性沥青,并对比FH改性沥青、SBS改性沥青和SBR改性沥青的低温抗裂性能,结果表明:FH改性沥青的低温抗裂性能比SBS改性沥青高,介于SBS和SBR改性沥青之间,且高温性能高于SBR改性沥青,满足要求。
FH modified asphalt is formed using SBS and SBR modifier.Comparing the low-temperature crack resistance of FH modified asphalt,SBS modified asphalt and SBR modified asphalt,the results show that the low-temperature crack resistance of FH modified asphalt is higher than SBS modified asphalt,but lower than SBR modified asphalt,meanwhile its high-temperature performance is better than SBR modified asphalt.It can meet the application requirement.
