摘　　要：针对原子力显微镜(AFM)观测的沥青"蜂状结构",提出结合图像处理技术,利用分形维数对沥青微观结构进行定量分析。首先,通过实验获取基质沥青的AFM观测图像,分析"蜂状结构"的组成;再以不同老化程度的沥青为研究对象,借助Image-pro plus图像分析软件及Fractal fox分形软件对沥青AFM观测图像开展系统分析。结果表明,随着老化程度的提高,"蜂状结构"普遍增大,但所占总面积减少,结构总数也逐渐减少,分形维数则呈上升趋势。利用分形维数观察沥青的"蜂状结构"具有很高可行性,是一种新颖可靠的评价方法。For the quantitative analysis of the asphalt microstructure named ＂bee-structure＂observed by atomic force microscopy（AFM）,a new way was proposed with fractal dimension and image processing technology.All the images were obtained by using AFM firstly,and the constitution of the bee-structure was discussed afterwards.Two image softwares were used,including Image-pro plus and Fractal fox,to analyze AFM images of asphalt aged for different time.The results showed that ＂ bee-structure＂ generally became bigger,but all of its area was reduced with the aging time increased.The number of this structure was also gradually reduced while fractal dimension showed a rising trend.Fractal dimension provided a novel and effective opportunity to observe and evaluate the ＂bee-structure＂,which contributed to the better estimation way of＂bee-structure＂.
