In　this　study,　a　novel　approach　based　on　Munsell　value　was　established　to　reveal　the　relationship　between　the　aging　degree　and　color　vision　of　asphalt.　Five　different　asphalt　binders　were　treated　by　three　types　of　aging　protocols　such　as　thin　film　oven　test　(TFOT),　pressure　aging　vessel　(PAV),　and　ultraviolet　(UV)　radiation,　then　the　effects　of　each　aging　treatment　on　the　ductility　and　color　spectrum　(collected　by　a　spectrometer,　AvaField-3)　of　the　binders　were　studied.　The　results　show　that　the　ductility　of　five　binders　is　decreased　after　the　three　aging　modes　(including　TFOT,　PAV　and　UV　aging),　nevertheless,　the　Munsell　values　show　different　behaviors,　they　become　smaller　after　TFOT　and　PAV　aging　while　becoming　larger　after　UV　aging.　Scanning　electron　microscope　(SEM)　photographs　show　that　the　UV　aging　leads　to　a　transformation　of　the　binder’s　surface　from　smooth　to　pleated,　thus　the　specular　reflection　of　the　asphalt　surface　changes　into　diffuse　reflection,　resulting　in　an　increase　in　Munsell　value　of　asphalt　after　UV　aging.　Meanwhile,　the　variation　of　Munsell　value　for　the　asphalt　after　UV　aging　is　larger　than　that　for　asphalt　after　thermal　oxidative　aging,　resulting　in　the　increase　of　Munsell　value　of　asphalt　which　undergoes　thermal　oxidative　aging　and　UV　aging.　Based　on　field　data　collection　and　analysis,　a　linear　regression　equation　(R　2　=　0.915)　is　established　between　the　Munsell　value　and　the　service　life　of　asphalt　pavement,　which　shows　that　the　asphalt　pavement　will　become　white　with　the　service　life-prolonging.　Based　on　this　study,　the　method　of　Munsell　value　can　be　a　promising　approach　to　evaluate　the　aging　degree　of　asphalt　pavement.　©　2024,　The　Author(s),　under　exclusive　licence　to　Chinese　Society　of　Pavement　Engineering.
