h i g h l i g h t s Calcium alginate capsules with rejuvenator are proposed for self-healing asphalt. Individual rejuvenator droplets are stored in porous media inside the capsule. The capsules are able to survive the asphalt mixing and compaction period. Calcium alginate capsules are capable of local crack healing in asphalt mix.

In recent decades, researchers have revealed the great healing potential of asphalt and proposed various novel methods to inspire and improve the self‐healing capacity of asphalt aimed to prolong the service life of asphalt pavement. In this review, up to date research progresses in induction healing and embedded rejuvenator encapsulation are presented, respectively. Meanwhile, the trial section applications of induction healing and capsule healing are highlighted, which show promising results. Finally, some recommendations for the future development of self‐healing asphalt are proposed.
