Abstract Accurate determination of adhesion between asphalt binders and aggregates is essential to the performance of pavement structures. In this study, particle probe scanning force microscopy was used to measure the adhesion between mineral microspheres representing the primary aggregate constituents and various control and modified binders. Average unit surface energies were applied to distinguish adhesion between various aggregate-binder pairs. Results showed that the alumina-binder pair exhibited higher adhesion than those of silica-binder and calcium carbonate-binder pairs. Microstructure variations were also detected for different modified binders that could lead to the adhesion differences.
