To this aim, the calcium alginate capsules encapsulating rejuvenator were manufactured and proved to have sufficient thermal stability and mechanical resistance to survive the asphalt production and compaction process. In this research, the healing effect of calcium alginate capsules were investigated in porous asphalt concrete. X-ray computed tomography (XCT) was used to visualize the distribution of capsules in porous asphalt concrete. A damaging and healing programme was carried out to evaluate the healing efficiency of these capsules. Semi-circular bending (SCB) tests was employed as a damaging process to investigate the fracture resistance of the porous asphalt concrete samples. The results showed that calcium alginate capsules were able to improve the healing capacity of porous asphalt concrete.
