Abstract To investigate how intermolecular forces in asphalt influence its pavement performance. Methylation and carboxylation methods were used to modify the asphaltene fraction of SK70# asphalt chemically. Fourier transform infrared spectroscopy (FTIR) was employed for semi-quantitative analysis of the chemically modified asphalt, helping to confirm the modification’s success. The Hansen solubility parameters(HSP) were used to quantify intermolecular interactions within the chemically modified asphalt. Then rutting factor, mean recovery rate (R), and non-recove-rable creep compliance (J_nr) were used to assess the high-temperature performance of various asphalt samples. A correlation analysis was then conducted to explore the relationship between the microscopic parameters of intermolecular interactions and the macroscopic indicators of pavement performance. The results show that methylation reduces the active hydrogen content in the asphalt, thereby decreasing its intermolecular polarity and the strength of hydrogen bonding. In contrast, carboxylation increases these properties. The chemical modifications increase the number of carbon atoms within the asphaltene, which enhances the polarization rate and dispersion forces of the asphalt molecules. Correlation analysis reveales that both modified asphalts’ rutting factors, R and J_nr, are closely associated with the HSP parameters’ hydrogen bonding component (H). This highlights that methylation weakens the hydrogen bonding interactions in the asphalt, resulting in a looser structure, decreases high-temperature rutting resistance, and reduces elasticity. Conversely, with sufficient levels of carboxylation, the asphaltene molecules become more associated, transitioning from smaller colloidal particles to larger aggregated structures. This results in an initial increase in elasti-city, followed by a decrease.
