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‐proplus图像分析软件及Fractalfox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。
針對原子力顯微鏡（AFM）觀測的瀝青“蜂狀結構”，提齣結閤圖像處理技術，利用分形維數對瀝青微觀結構進行定量分析。首先，通過實驗穫取基質瀝青的AFM觀測圖像，分析“蜂狀結構”的組成；再以不同老化程度的瀝青為研究對象，藉助Image‐proplus圖像分析軟件及Fractalfox分形軟件對瀝青AFM觀測圖像開展繫統分析。結果錶明，隨著老化程度的提高，“蜂狀結構”普遍增大，但所佔總麵積減少，結構總數也逐漸減少，分形維數則呈上升趨勢。利用分形維數觀察瀝青的“蜂狀結構”具有很高可行性，是一種新穎可靠的評價方法。

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” .
