Understanding　of　the　healing　behavior　of　asphalt　binder　is　critical　for　fatigue　modeling　of　asphalt　paving　materials.　Binder-healing　characterization　based　on　the　traditional　time　sweep　test　is　time-consuming.　The　purpose　of　this　study　was　to　compare　the　damage-healing　behavior　of　various　neat　and　modified　asphalt　binders　with　the　newly　developed　linear　amplitude　sweep　healing　(LASH)　procedure,　followed　by　verification　on　a　simplified　LASH　(S-LASH)　procedure　to　alternatively　estimate　binder-healing　characteristics　with　reasonable　testing　efficiency.　Thirteen　neat　and　modified　asphalt　binders　(17　sample　conditions)　were　selected　and　respectively　analyzed　with　standard　LASH　and　S-LASH.　Standard　LASH　showed　that　the　healing　performance　of　neat　binders　with　the　same　penetration　grade　generally　aligns　with　increasing　damage.　For　the　neat　binders　with　different　penetration　grades,　softer　binders　have　better　healing　capacity.　The　negative　aging　effect　on　binder　healing　was　demonstrated.　Meanwhile,　the　healing　master　curve　(HMC)　was　effective　in　comparing　binder-healing　characteristics　under　prefailure　conditions.　The　healing　rate　(H-R)　for　the　tested　binders　basically　varied　from　0.1　to　0.2.　Finally,　mean　absolute　error　(MAE)　analysis　of　HMC　and　H-R　between　standard　LASH　and　S-LASH　indicated　50%　S-f　(damage　intensity　at　failure)　with　a　900-s　rest　period　to　be　a　critical　LASH　testing　condition　to　derive　reliable　healing　HMC　and　H-R　values.　S-LASH　is　also　recommended　to　estimate　binder　healing　characteristic　with　significantly　reduced　testing　time.　(C)　2021　American　Society　of　Civil　Engineers.
