- Abstract:
- In this paper, the dynamic modulus of pyrolysis carbon black （PCB） modified asphalt mixture was tested by the simple performance tester (SPT). The influence of different temperature and load frequency on dynamic modulus and phase angle of the asphalt mixture was investigated. The dynamic modulus and phase angle master curves were fitted by numerical method to analyze the viscoelastic characteristic of PCB modified asphalt mixture. Experimental results showed that the dynamic modulus and phase angle of PCB modified asphalt mixture were dependent on the change of temperature and load frequency. At lower temperature and higher frequency, the dynamic modulus of asphalt mixture increased but phase angle decreased greatly with the addition of PCB, indicating that the elastic behavior of PCB modified asphalt mixture was enhanced while the viscous behavior was weakened. At higher temperature and lower frequency, the PCB showed little influence on the viscoelastic characteristic of asphalt mixture.
