摘要:
采用简单性能试验机对废橡胶裂解炭黑(PCB)改性沥青混合料进行了动态模量试验,研究了不同温度与荷载频率对其动态模量和相位角的影响,通过数值分析方法,拟合了PCB改性沥青混合料的动态模量和相位角主曲线,分析了PCB对沥青混合料粘弹特性的影响。结果表明:PCB改性沥青混合料的动态模量和相位角依赖于温度和荷载频率的变化:低温和高频时,PCB的加入使得沥青混合料的动态模量明显增大,相位角明显减小,弹性特征增强,粘性特征减弱;高温和低频时,PCB对沥青混合料粘弹性的影响不明显.
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.
