荧光显微分析方法量化改性沥青性能的研究

Quantitatively Analysis on Modified Asphalt by Fluorescent Microscope

利用荧光显微镜、图像采集系统、专业分析软件可以方便、准确地观测改性沥青的微观结构。利用两种基质沥青与两种改性剂以不同的剂量分别制备改性沥青,通过显微分析技术得到改性沥青的微观结构、常规试验方法得到改性沥青的技术性能指标、回归分析建立了改性沥青的微观结构与使用性能之间的关系。结果表明这种方法获得的改性沥青微观结构与改性沥青的宏观性能有很好的相关性,微观结构分析方法可以量化改性沥青的性能。

Using fluorescent microscope, image collecting system, professional software, the microsrtucture of modified asphalt can be observed conveniently and accurately. In this research, two kinds of SBS modifier with different doses were put into two types of matrix asphalt. Then its microstructure was observed by microscopic analyses technical , its performance index was got by technical test methods. Using regressive analyses method, the relationship between microstructure and technical performance of modified asphalt was eatablished. The cxperimenatl ersults showed that this structure was consanguineous related with the rechnical performance of modified asphalt, microstructure of modified asphalt can be uqantitatively analyzde.
