Abstract

The Binder-Fast-Characterization-Test in the DSR can be used instead of conventional test methods for characterizing plain and modified asphalt binders in the high temperature range. The test is called “Bitumen-Typisierungs-Schnell-Verfahren (BTSV)” and was recently introduced to the German standards. With two rheological key parameters (TBTSV and δBTSV), asphalt binders can be differentiated in regard to hardness and degree of modification. This study presents possible applications of the procedure. The test method can be used to clearly characterizing virgin unknown asphalt binders and to differentiate between modified and unmodified binders. In addition, the two key parameters can be used to evaluate aged asphalt binders and the ageing susceptibility. A linear change of the two key parameters was detected for ageing and blending processes of asphalt binders. Thus, the effectiveness of different rejuvenating materials can be evaluated and necessary amounts of rejuvenator identified to produce target binders with specific rheological properties in the high temperature range.
