15 HYPOTHESIS The physical properties of thin asphalt films on mineral aggregates are not completely predictable from experiments using thick (1.0 mm) films on steel surfaces, which is the methodology employed in the current Superpave rheological specifications.
16 OBJECTIVE To develop a simple method that enables the interactions between thin asphalt layers and various aggregate surfaces to be measured.

40 CONCLUSIONS Polar asphalt components interacting with a mineral substrate induce multimolecular structuring in thin films producing an increase in viscosity. Interactions of asphalts with mineral surfaces have dramatic effects on thin-film viscosities. The interactions depend on asphalt composition and aggregate surface composition.
41 CONCLUSIONS The effects of aggregate surface-induced structuring on the rheological properties of asphalt binders in the thin film region at the asphalt-aggregate interface can be measured by the specially designed fixture. It appears that the specially designed fixture can also be employed to evaluate the effect of water on the rheological properties of thin films of asphalt.
