摘要

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性能分析为提高沥青使用寿命提供了理论依据。分子间的相互作用对沥青这一胶体材料的宏观性能产生了重大影响,导致表征沥青分子结构的参数无法与沥青的力学性能直接联系起来。本文介绍了超分子理论,简要回顾了现有的沥青超分子模型和研究方法,旨在探索一种研究沥青微观结构和宏观性能的新方法。结果表明,超分子理论关注的是分子间的相互作用,为研究沥青超分子提供了更准确的指标。沥青的超分子分析提出了可行的方法,并与沥青的性能建立了良好的联系,为理解沥青的微观结构提供了一个新的视角,为捕捉沥青的力学行为提供了一种新的途径。

Research progress on supramolecular structures of asphalt

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.
