文摘

Asphalt surface tension is related to the aromatic and asphaltenes content. Asphalt viscosity and asphaltenes content impact equilibrium contact angles. Substrate heterogeneities improve wetting quality on mineral surfaces. A complete characterization of mineral substrates by SEM is highly recommended. The CBOW model is a promising approach to characterize substrate heterogeneity.
