Polymeric modifiers are added to improve the performance of different binders. Thus, it is essential to characterize quantitatively the adhesion between modified binders and aggregates. In this study, a scanning force microscope with particle probes was used to measure the adhesion between the control binder PG 64-22 and three modifications using styrene–butadiene rubber, polyphosphoric acid, and styrene–butadiene–styrene. Unit surface energies were used to distinguish the adhesion between modified binders. Results showed that the adhesion between alumina particles and binders increased as weight percentages of the modifier increased. However, no monotonic trends were observed for the adhesion between silica or calcium carbonate particles and binders. The surface morphologies of the modified binders were different from those of the control binder as a result of modifications.
