Adsorption of model compounds containing functionalities thought to play an importantrole in the interaction between asphalt and aggregate was conducted using a silica as amodel substrate. Dimethylsulfoxide, 1-butanol, triethylamine, propionic acid, 2-butanone, ethylacetate andnaphthalene were selected as model compounds. Adsorption parameters such as themonolayer amounts and the standard free energy changes of model compounds wereestimated by applying the Langmuir model and the Freundlich model to the adsorptionisotherms. Based on these results, the adsorption behavior of model compounds was brieflydiscussed.
