The　overall　rigidity　of　the　cement　concrete　pavement　is　high,　but　there　are　defects　such　as　easy　cracking　and　insufficient　anti-slip　performance.　The　epoxy　resin　ultra-thin　wearing　course　overlay　can　effectively　solve　these　issues.　However,　there　is　still　a　lack　of　knowledge　about　the　long-term　performance　of　epoxy　resin　ultra-thin　wearing　course　overlay　on　cement　concrete　pavement.　Therefore,　this　article　analyzed　the　interlayer　adhesion　and　durability　of　epoxy　resin　ultra-thin　wearing　course　overlay　through　the　Hamburg　rutting　test　and　a　series　of　shear　tests　under　damp　heat,　thermal　oxygen　aging,　and　ultraviolet　(UV)　aging　conditions.　Shear　test　results　indicated　that　the　shear　performance　of　epoxy　resin　overlay　grew　with　the　increase　in　epoxy　resin　content　and　was　severely　affected　by　high　temperature,　and　the　optimal　content　was　set　as　3.4　kg/m2.　The　Hamburg　rutting　test　results　showed　that　the　epoxy　resin　overlay　exhibited　satisfactory　high-temperature　performance　and　water　resistance.　For　the　damp　heat　effect,　it　was　revealed　that　damp　heat　led　to　more　significant　shear　strength　loss　compared　with　the　overlay　specimens　without　damp　heat.　The　water　immersion　caused　the　shear　strength　decline　due　to　the　water　damage　to　the　overlay　interface.　As　for　the　thermal　oxygen　aging　effect,　it　was　reflected　that　the　short-term　thermal　oxygen　aging　had　a　minor　impact　on　the　shear　performance　of　the　epoxy　resin　overlay.　However,　with　the　increase　in　thermal　oxygen　aging　duration,　the　shear　strength　of　the　epoxy　resin　overlay　significantly　decreased　due　to　the　aging　of　epoxy　resin　binders.　Regarding　the　UV　aging　impact,　it　was　also　found　that　the　shear　performance　of　the　epoxy　resin　overlay　rapidly　decreased　as　the　UV　aging　duration　grew　whether　at　20　°C　or　60　°C.　Moreover,　UV　aging　led　to　a　more　significant　impact　on　the　shear　performance　of　the　epoxy　resin　overlay　than　thermal　oxygen　aging.　©　2023　by　the　authors.
