摘要:
采用原子力显微镜研究新旧沥青融合再生过程中不同区域的微观形态结构特征及力学性质，探索新旧沥青融合再生过程中微观形态结构的演变规律.利用分析软件提取新旧沥青及其融合区沥青微观结构的形态学参数并进行量化分析，研究再生沥青微观形态学参数与其力学性质的关系.
Abstract:
The paper analyzed the microstructure characteristics and mechanical properties by using atomic force microscopy (AFM) to explore the evolution law of microstructure in the diffusion process of the virgin asphalt and aged asphalt, to ascertain the mechanism of blending between virgin and aged asphalt. The relationship between microcosmic morphology parameters and mechanical properties of recycled asphalt was studied by means of quantitative analysis of microcosmic morphology parameters for virgin and aged asphalt extracted by analysis software. The results showed that part of asphaltene was dissolved so that the number of “bee” structure reduced and the volume of “bee” structure increased, so as to increase the distance between each other and reduce the interaction force. The dense mesh structure became loose and modulus of asphalt reduced. What′s more, the morphological parameters and mechanical indexes of fusion area were between aged and new asphalt.
