The use of black carbon obtained by nano zirconium dioxide and pyrolysis in the modification of bitumin and investigation of the reological properties

The use of traditional bitumen in asphalt within the framework of traffic and climatic conditions is sufficient in terms of adhesion and mechanical properties. However, changing traffic and climatic conditions over time leave negative effects on the coating. Bitumen modification is required to minimize the adverse effects. The aim of this thesis study is to modify bitumen with carbon black and nano zirconium dioxide (NZrO₂) obtained from pyrolyzed wate vehicle tires, to investigate the usability along with performance and engineering properties of additives in bituminous hot mixture and to examine the effects of these additives on the rheological properties of bitumen as well. In this study, the penetration, softening point, flash point, dynamic shear rheometer (DSR) and The Rolling thin film ovens tests (RTFOT) of all samples has been applied by adding %1ALY+%1NKO and %2ALY+%2NKO and %3ALY+%3NKO in terms of weight into black carbon (BC) and nano zirconium dioxide (NZrO₂) 70/100 penetration pure bitumen obtained from end-of-life tires. Penetration, softening point and DSR tests have been applied to samples aged with RTFOT. By applying beam bending rheometry (BBR) experiments after aging with RTFOT+PAV (a pressure aging vessel), the change in the rheological properties of bituminous binders has been observed. As a result, it has been observed that as the amount of additives increases, the temperature sensitivity of the bituminous binder gradually decreases and the bitumen can be used in warmer places, the tire mark resistance increases accordingly, and it is resistant to thermal cracks at low temperatures as well.
