Healing　characteristics　of　asphalt　lay　a　foundation　for　the　wide　applications　of　permanent　roads.　However,　the　decay　pattern　of　asphalt　healing　ability　in　actual　climate　environments　still　remains　unclear.　Hence,　the　weather　accelerated　ageing　(WAA)　influence　on　the　healing　temperature　sensitivity　of　several　representative　asphalts　is　systematically　investigated　in　this　paper.　Results　from　fatigue-healing-fatigue　(FHF)　experiment　show　that　the　WAA　and　terminal　blend　crumb　rubber　(TBCR)　modification　impart　pronounced　impacts　to　the　healing　temperature　sensitivity　of　asphalts.　Notably,　it　is　found　that　the　aged　asphalt　has　a　healing　inertia　zone　with　low　healing　temperature　sensitivity,　in　which　the　healing　ability　of　asphalt　is　at　a　relatively　low　level.　Furthermore,　four　kinds　of　various　index　temperatures　are　put　forward　as　the　evaluation　indicators　to　quantitatively　characterize　the　influence　of　WAA　on　the　healing　temperature　sensitivity,　i.e.　inert　extended　temperature　at　healing　rate　curve,　inert　extended　temperature　at　healing　percentage　curve,　top　healing　temperature　(THT)　shift　value　and　complete　healing　temperature　range　(CHTR)　shift　value.　Moreover,　the　greater　the　WAA　resistance　of　asphalt,　the　smaller　the　WAA　influence　on　its　healing　temperature　sensitivity.　The　WAA　reduces　the　differences　of　healing　temperature　sensitivity　among　various　asphalts.　Lastly,　the　thermal　stability　and　phase　behavior　investigations　reveal　that　the　molecular　compositions　and　phase　state　transition　(PST)　of　asphalt　will　be　changed　after　WAA,　eventually　inducing　the　healing　temperature　shift　and　the　appearance　of　healing　inertia　zone.　(C)　2020　Elsevier　Ltd.　All　rights　reserved.
