To restore the necessary properties of the aged asphalt, rejuvenating additives can be used. However, to successfully soften the oxidized binder and reach uniform dispersion within the asphalt to ensure required performance properties and longevity of the mixture, an appropriate dosage of a compatible rejuvenator has to be introduced. The application has to be carefully studied to improve the cracking performance without increasing the susceptibility to rutting and ensuring structural stability.
