Abstract
Abstract Advancing sustainable materials requires addressing their environmental impacts, particularly emissions. This study contributes to the development of sustainable, non‐emitting asphalt by providing a detailed understanding of the diffusion and adsorption behaviors of hazardous organic compounds (HOCs) emitted from asphalt. Using molecular simulations and quantum analysis, it is investigated how the diffusion and adsorption characteristics of sulfur‐ and oxygen‐containing HOCs change as aging progresses in asphalt. The results show that oxidation reduces the diffusion rate of HOCs and increases their adsorption energy. Dispersion forces and electrostatic attractions are key mechanisms stabilizing HOCs…
