Oxidative　aging　induces　significant　stiffening　of　asphalt　binders　that　leads　to　a　pronounced　reduction　in　the　overall　durability　of　asphalt　pavements.　The　strategic　implementation　of　antioxidant　additives　provides　a　potential　solution　to　alleviate　this　issue.　This　work　presents　results　from　the　second　phase　of　the　global　consortium　for　antioxidants　research　aimed　at　investigating　the　effectiveness　of　potential　antioxidants　in　increasing　the　durability　of　asphalt　binders.　Sixteen　laboratories　around　the　world　participated　in　this　effort　and　a　total　of　28　binders　from　diverse　geographical　regions　were　tested.　Two　promising　antioxidants,　namely　zinc　diethyldithiocarbamate　(ZDC)　and　kraft　lignin　were　evaluated　in　this　phase　and　blended　with　the　binders　at　specific　proportions.　Subsequently,　a　comprehensive　investigation　was　conducted　to　assess　rheological　characteristics　and　chemical　properties　of　the　various　blends,　utilising　Dynamic　Shear　Rheometer　(DSR)　measurements　and　Fourier　Transform　Infrared　(FTIR)　Spectroscopy.　The　findings　indicate　that　additives　such　as　ZDC　hold　considerable　promise　as　an　effective　antioxidant,　particularly　when　considering　a　wide　diversity　of　binders.　In　general,　its　incorporation　does　not　compromise　the　rutting　performance　of　the　binders　and　significantly　improves　fatigue　performance.　Therefore,　research　efforts　should　be　focused　on　exploring　additional　facets　to　assess　its　practical　applicability　in　field.
