Long-Term Ageing Resistance of Bio-Based Rejuvenated Asphalt Mix Against Cracking
The ageing behavior of asphalt mixtures containing RAP and rejuvenators and its effects on the performance properties of the asphalt mixes have not yet been systematically investigated. In this study, three types of asphalt mixes with three different bio-based rejuventors and with a soft paving grade bitumen 160/220 (reference variant R0) were investigated. In order, to find out the ageing resistance of rejuvenated asphalt, the performance properties of asphalt mixes were determined before and after the long-term ageing of asphalt mixes. The resistance of asphalt mixes against low temperature deterioration was investigated by means of the thermal stress restrained specimen test (TSRST), uniaxial tensile test (UTST) and fatigue cracks by means of indirect tensile test (ITT).
The determined performance properties of asphalt after ageing show that asphalt mixes with RAP and rejuvenators can have better performance at low temperature and similar fatigue properties compared to asphalt mixes produced with virgin material.
