The paper analyzes the performance of polymer modified bitumen due to multiple stress creep recovery (MSCR). This phenomenon is of great importance when considering binder’s performance related to rutting resistance on high temperatures during exploitation period. The paper presents testing results of five polymer modified bitumen samples, obtained by two producers, tested under same temperature and stress levels. Finally, bitumen samples are classified under new MSCR specification, according to SUPERPAVE methodology.
