This study evaluated the effects of aging and moisture on the adhesion properties of asphalt-aggregate interfaces. The work of adhesion obtained from molecular dynamics (MD) simulations and atomic force microscopy (AFM) tests were compared. The adhesive forces of asphalt before and after immersing in water were obtained by the peak force tapping quantitative nanomechanical (PFT-QNM) mode of AFM tests. Results showed that the average size of bee structures became larger after aging. The adhesive forces of the para-phase were the highest. A strong correlation was found between the adhesion properties obtained from MD simulations and AFM tests. The increase in asphaltene index could improve the adhesion, whereas the changes in molecular structures due to oxidative aging would weaken it. The balance of changes in them determined the overall adhesion properties. After immersing in water, the adhesion properties of aged asphalt were more susceptible to moisture damage.

本研究评估了老化和水分对沥青-集料界面粘合性能的影响。比较了从分子动力学 (MD) 模拟和原子力显微镜 (AFM) 测试中获得的粘附作用。通过AFM测试的峰值力敲击定量纳米力学（PFT-QNM）模式获得浸水前后沥青的附着力。结果表明，蜜蜂结构的平均尺寸在老化后变大。对相的粘附力最高。在从 MD 模拟和 AFM 测试中获得的粘附性能之间发现了很强的相关性。沥青质指数的增加可以提高粘附性，而由于氧化老化引起的分子结构变化会削弱其粘附性。它们的变化平衡决定了整体的粘合性能。浸水后，老化沥青的附着力更容易受到水分的破坏。
