沥青结合料的性能对沥青路面的设计寿命起着至关重要的作用。基于化学结构的沥青力学行为分析为提高沥青使用寿命性能提供了理论依据。沥青是一种胶体材料，分子间相互作用对沥青的宏观性能有着重要的影响，导致表征沥青分子结构的参数不能直接与沥青的力学性能联系起来。介绍了超分子理论，对现有的沥青超分子模型和研究方法进行了简要综述，旨在为沥青微观结构与宏观性能的研究探索一种新的方法。结果表明，超分子理论关注的是分子间的相互作用，为沥青超分子的研究提供了更准确的指标。沥青的超分子分析提供了可行的方法，并与沥青的性质建立了良好的联系，为理解沥青的微观结构提供了新的视角，为捕捉沥青的力学行为提供了新的途径。
The properties of asphalt binder play an essential role in the design life of asphalt pavement. Analysis of asphalt mechanical behaviors based on the chemical structures provides the theoretical basis for the improvement of asphalt performance in service life. Intermolecular interactions have a significant impact on the macroscopic properties of asphalt, a colloidal material, resulting in the parameters characterizing asphalt molecular structures fail to directly connect with mechanical properties of asphalt. This paper introduces the supramolecular theory, presents a brief review of existing supramolecular models and research methods of asphalt, aiming to explore a new methodology for the investigation between asphalt microstructures and macroscopic properties. Results showed the supramolecular theory focuses on the intermolecular interactions, providing more accurate indicators for the investigation on the asphalt supramolecules. Supramolecular analysis of asphalt has proposed feasible methods and established favorable connections with asphalt properties, giving a new view of understanding asphalt microstructure and a new approach to capture mechanical behaviors of asphalt.
