Abstract

The performance of asphalt binders at high and low temperatures has an important role on the rutting and cracking
resistance of asphalt pavements. Crumb Rubber Modified (CRM) is one of the asphalt modifiers that improves asphalt
physical and mechanical properties and helps reducing environmental pollution. In this research, three unmodified
and six CRM modified binders were tested using the Superpave test and Performance Grading (PG) system. The Multiple
Stress Creep and Recovery (MSCR) test was used to assess rutting resistance of rubberized binders. The study
compared the results of this classification with the 7 performance grade binders required for specific climatic zones
in Isfahan Province. The results show that, CRM improves asphalt’s physical and mechanical properties at service
temperatures and decrease in the non-recoverable compliances (Jnr) in MSCR test. Moreover, CRM binder is sufficient
for the required PGs, while based on MSCR test, it cannot fully cover the traffic level requirements in Isfahan
Province.
