Polyurethane-modified asphalt mechanism
Published 2025-07-01“…The feasibility of using polyurethane as a modifier and its effects on matrix asphalt were analyzed using scanning electron microscopy, Fourier transform infrared spectroscopy, and atomic force microscopy. Additionally, molecular dynamics simulations were employed to analyze the radial distribution function, adhesion energy, and cohesive energy density of asphalt before and after the addition of polyurethane at the microscopic structural level, revealing the molecular motion trends and interfacial bonding forces of the four components of asphalt.The results indicate that the incorporation of polyurethane leads to changes in the absorption peaks of matrix asphalt, a reduction in the ''honeycomb'' structure, and shrinkage. …”
