The paper presents results of testing the adhesion between asphalt binder and aggregate.
Methods of testing adhesion between bitumen and aggregate were described.
In this work the influence of the aging of modified asphalt binders on adhesion was tested. Several types of polymer-modified asphalt and aggregate were investigated.
Two methods of aging: the Thin Film Oven Test (TFOT) and the Pressure Aging Vessel (PAV) were used.
Adhesion was determined by the modified boiling test.
Computer image analysis was used for qualitative and quantitative evaluation of adhesion between bitumen and aggregate.
Effect of the polymer modification on adhesion was discussed.
