Evaluation of bitumen's fatigue resistance - a comparative study within Weave-UNISONO 2021 project, NCN project No 2021/03/Y/ST8/00079, and GACR project GA22-04047K

Summary:

Three asphalt binders were tested, two paving grade bitumens 35/50 and 50/70 and PMB 25/55-60. Basic characteristics were determined for all binders in three stages: original and after short-term and long-term ageing. The short-term ageing was performed using the RTFOT procedure, and the long-term ageing was performed using the PAV method. The shear stress Superpave fatigue tests, long-time-sweep, and LAS were conducted using a Dynamic Shear Rheometer (DSR) with parallel plates of 8 mm in diameter and a gap of 2 mm in a long-term PAV-aged state.
