摘要
通过原子力学显微镜下AFM图像中蜂状结构的组成、生长机理,沥青AFM分析试件制备方法以及蜂状结构对沥青力学性能、抗老化性能、自愈合性能的影响分析,并对AFM力曲线推导沥青黏附功和沥青集料黏附功检测中沥青抗水损害性能进行分析,以此评价沥青混合料的抗水损害性能,有利于对沥青的选择。
The composition and growth mechanism of the bee structure can be studied by atomic force microscopy(AFM), the preparation method of asphalt sample for AFM analysis and the relationship between bee structure and mechanical properties, anti-aging performance and self-healing properties were also studied. In addition, how to use force curve to obtain the adhesive work of asphalt and the adhesive work between asphalt and aggregate, researched on the water damage of asphalt microstructure with AFM image so as to judge the anti-water damage of asphalt mixtures. Results of this paper can be used for detecting microscopic structure and microanalysis of asphalt with AFM.
