摘　　要：为提高中国沥青路面的研究技术,着重从本构模型与微观结构方面综述了近20年来沥青及沥青混合料的研究现状与发展前景。对沥青的组分、分子结构、本构模型及结构研究的新动态进行了总结;对沥青混合料的本构模型、微观结构、多尺度模拟、虚拟试验法、有限单元模型及微观结构分析中的数学力学方法进行了梳理。分析结果表明:利用现代科技手段研究沥青及沥青混合料微观结构的力学行为,可揭示许多用常规方法难以发现的问题和规律;沥青混合料的本构模型为实际荷载作用下沥青混合料的力学性能提供了更准确的信息,为建立材料特性与模型参数之间的关系提供了支撑。In order to improve research technologies on asphalt pavement in our country,the current research situation and the development prospects of asphalt and asphalt mixture in the recent 20 years were reviewed mainly in the aspects of the constitutive model and microstructure.Firstly,new trends of the researches on components,molecular structures,constitutive model and structure of asphalt were summarized.Secondly,the constitutive model,the microstructure,the multi-scale simulation,the virtual experiment,the finite element model and the mathematic mechanic method in microstructure analysis of asphalt mixture were investigated.The results show that the researches on the mechanic behavior of microstructure of asphalt and asphalt mixture with the application of modern technologies can unveil problems and regularities that many conventional methods fail to discover;the constitutive model of asphalt mixture can provide more accurate information about the mechanic performance of asphalt mixture under actual loading conditions,providing supports for building relationships between material properties and model parameters.
