Original Abstract

Paper deals with a potential presence of visbreaking residues in commercially available paving grade bitumens, and their impact on the thermooxidative properties of the bitumen. All of the tested bitumens were submitted to the accelerated ageing procedure. The changes in parameters caused by the ageing process were determined by means of a dynamic shear rheometer (DSR) and bending beam rheometer (BBR). The inner chemical compatibility was determined by single point precipitation titration. The obtained data were subsequently compared with the results from laboratory prepared binders, which contained a known portion of visbreaking residues. The results showed that the presence of visbreaking residues has a negative impact on the properties of paving bitumens, especially with respect to their thermooxidative ageing.
