摘　　要：废胶粉改性沥青的存储稳定性能是影响橡胶粉改性沥青性质的重要因素,也是研究人员长期试图解决的问题。通过采用离析试验、荧光显微分析和傅立叶变换红外光谱(FTIR)等手段来评价废胶粉改性沥青的相容性,并且探讨离析的机理,研究结果表明:废胶粉改性沥青的离析程度会受储存时间、温度等贮存条件的影响,但是最主要的影响因素还是基质沥青的自然特性与改性剂的性质、剂量。The storage stability of CRM（crumb rubber modified） asphalt is an important factor which affects its performance. It＇s also a long-term problem for the researchers to solve. Isolation experiment, fluorescent microscope and Fourier transform infrared absorption spectrum analysis are used to evaluate the compatibility and the modified mechanism of CRM. Research fruits show that the segregation extent of CRM is mostly influenced by the properties of asphalt and the dozes of modifier in addition to the condition of storage, such as time and temperature.
