Evaluation of Interaction Ability between Asphalt and Mineral Powder through Adsorbed Asphalt Film Thickness Based on Micromechanics Approach
The thickness of adsorbed asphalt film is used to evaluate the interaction ability between asphalt and mineral powder. The calculation methods of the thickness of adsorbed asphalt film are proposed based on the Hashin, Mori Tanaka, and generalized self-consistent model, respectively. The influences of the acidity and alkalinity of mineral powder, test temperature, and frequency on the interactions are analyzed. The results show that the thickness of adsorbed asphalt film calculated by the Hashin model can better evaluate the interaction between asphalt and mineral powder. The higher the content of acid SiO₂ in mineral powder, the weaker the interaction ability between asphalt and mineral powder. The large amount of SiO₂ contained in coal gangue mineral powder inhibits the interaction ability with asphalt.
