Effects of waste engine oil and crumb rubber rejuvenator on the performance of 100% RAP binder

It is frequently essential to add rejuvenators recycled mixtures comprising reclaimed asphalt pavement (RAP) increase their performance. In this research, CR was desulfurized using WEO produce a compound rejuvenator. The mixes containing 100% RAP binder were modified and rejuvenated with 0%, 3%, 6%, 9%, 12% WEO-CR. performance of the HMA samples assessed Marshall stability-flow test, indirect tensile strength (ITS) wheel-tracking device. results showed that 9% WEO-CR rejuvenator restores physical properties aged binder. addition, findings revealed adding increased tested samples; however, for long-term HMA, may adversely affect mixture. Therefore, addition found improve overall mixture which improved chemical enhanced mechanical compared control
