This　study　investigated　the　effect　of　seven　healing　agents　on　crack　healing　ability　of　long-term　aged　asphalt　and　its　mortar.　Different　healing　agents　including　sunflower　oil,　aromatic　oil,　bitumen　emulsion,　and　maltene-based　emulsions　were　used.　The　crack　healing　of　asphalt　made　use　of　two　asphalt　disk　samples　and　healing　was　evaluated　using　direct　tensile　tests.　For　asphalt　mortar,　notched　semi-circular　samples　were　used.　Test　results　indicated　that　the　crack　healing　of　asphalt　and　its　mortar　depended　strongly　on　the　type　of　healing　agent.　In　general,　asphalt　healed　faster　than　its　mortar.　Asphalt　healing　could　be　well　improved　by　using　oil　agents,　while　asphalt　mortar　could　be　well　healed　with　maltene-based　emulsions.　The　crack　healing　of　asphalt　mortar　developed　rapidly　followed　by　a　steady　state　of　increase.　Initial　crack　healing　using　healing　agents　could　be　contributed　by　the　diffusion　and　softening　effects,　which　resulted　in　low　strength　recovery.　Long　term　healing　could　lead　to　the　bonding　reconstitution　in　the　cracks,　which　were　decisive　for　the　final　strength　gain.　The　promising　healing　agent　should　be　able　to　achieve　maximum　strength　recovery　to　resist　cracking　as　well　as　a　sufficient　re-healing　ability　to　deal　with　crack　opening　and　closing.
