Research on High-RAP Asphalt Mixtures with Rejuvenators ...

Addition of rejuvenators to the mixture of recycled asphalt binder and virgin binder led to a decrease in the amount of asphaltenes. Furthermore, rejuvenators improved colloidal instability index (CII), which implies that the aged binder has become more stable due to rejuvenation.

Mixture tests showed a promising effect of rejuvenators as they did not soften high-RAP mixture excessively, so all samples passed HWT test. From the DCT test, it can be concluded that rejuvenators (except one type) enhance the low-temperature cracking properties of asphalt mixtures without sacrificing the bond between aggregate and binder.

Aging of Rejuvenated Asphalt Binders

Jun 08, 2017  An important concern that limits the RAP content in asphalt mixtures is the fact that the aged binder that is present in the RAP can cause premature cracking. Rejuvenators are frequently added to high RAP mixtures to enhance the properties of the binder. There is no existing method to predict the longevity of a rejuvenated asphalt. This study investigated the
