Optimization of the Calcium Alginate Capsules for Self-Healing Asphalt

Applied Sciences, 2019
It has been demonstrated that calcium alginate capsules can be used as an asphalt healing system by pre-placing rejuvenator (healing agent) into the asphalt mix and releasing the rejuvenator on demand (upon cracking). This healing mechanism relies on the
