The role of rejuvenators in embedded damage healing for asphalt pavement

Materials & Design, 2021
Rejuvenator encapsulation technique showed great potential for extrinsic asphalt pavement damage healing. Once the capsules are embedded within asphalt pavement, the healing is activated on-demand via progressing microcrack.

Recent advances in calcium alginate hydrogels encapsulating rejuvenator for asphalt self-healing

Journal of Road Engineering, 2022
Summary: The inherent self-healing ability of asphalt is insufficient and fails to timely repair the cracks due to the combined effect of temperature variation, air oxidation, ultraviolet exposure and traffic loading.
