| Abstract: | 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. |
