The chemical composition of asphalt binder is closely related to its macroscopic properties, and as an important road building material, performance directly affects the service pavement. Saturate, aromatic, resin, asphaltene are four most common components binders, collectively known SARA components. used establish corresponding relationship between properties binder, which great significance for further research on development high-performance pavement materials. This study eight types virgin binders raw materials, labeled A–H. Firstly, thin-layer chromatography–flame ionization detection (TLC-FID) method was test contents different binders. Then, conventional, rheological, low-temperature were tested. Finally, gray relational analysis (GRA) Pearson correlation (PCA) binder’s content properties. results indicate that asphaltenes resins crucial in determining high-temperature binder. By adjusting ratio these components, can be optimized. An increase heavy particularly asphaltenes, negatively In contrast, a higher aromatic enhances performance.

Rubberised asphalt faces challenges such as viscosity and construction energy consumption. These problems can be ameliorated by the use of foaming technology. However, existing studies lack a microscopic-level understanding mechanism interfacial properties foam rubberised asphalt. Therefore, this study used molecular dynamics simulation methods to establish models interface models. The were analysed from aspects model density, change, agglomeration behaviour adhesion work. Results revealed that increased temperature water consumption caused difficulties in volumetric compression model. diffusion aggregation molecules altered distribution other model, effectively reducing without affecting chemical structure. In contribute migration mineral surface, which exists two forms: aggregating within diffusing interface. enhance electrostatic interaction between minerals. due random nature molecule diffusion, it is difficult form regular layer at interface, leads failure
