摘　　要：原子力显微镜(Atomic force microscope,AFM)不仅可以从纳米尺度观测沥青表面微观结构,还可以应用不同模式测试其微观力学特性,是研究沥青路面材料微观特性的有力工具。沥青混合料的水损害已经成为沥青路面的主要病害之一,研究表明,沥青结合料与集料之间的水分相互作用是一种出现在微观尺度,甚至纳米尺度的现象,因此从微纳观角度探究在水分存在条件下沥青与集料的结构变化,对于改善沥青混合料水稳定性能,探究其水损害机制具有深远的意义。本文在总结AFM工作原理及沥青微观“bees”结构特性的基础上,重点分析了AFM在纳米尺度上对沥青混合料水稳性能的研究成果,并探讨了AFM在沥青路面材料研究中的发展方向,为今后对于沥青路面病害研究与防治方面提供一定的借鉴。Atomic force microscope(AFM)not only observes the microstructure of asphalt surface at the nanoscale,but also measures the micro mechanical properties of asphalt by using the different modes.It is a powerful tool for studying the micro properties of asphalt pavement materials.The water damage of asphalt mixture has become one of the main diseases of asphalt pavement.Many research had shown that the water interaction between asphalt binder and aggregate was a phenomenon that occurred at the micro or even nano scale.Therefore,exploring the structural changes between asphalt and aggregates under the presence of moisture from a micro nano perspective had profound significance for improving the water stability performance of asphalt mixtures and exploring their water damage mechanisms.On the basis of summarizing the working principle of AFM and the microscopic‘bees’structural characteristics,this article focused on analyzing the research results of AFM on the water stability performance of asphalt mixtures at the nanoscale,and explores the development direction of AFM in the research of asphalt pavement materials,providing certain reference significance for future research and prevention of asphalt pavement diseases.
