Asphalt　concrete　is　the　main　material　consumed　by　road　engineering.　At　present,　there　is　no　uniform　standard　for　determining　the　carbon　emissions　of　different　types　of　asphalt　concrete,　and　the　calculation　process　is　uncertain.　In　this　study,　a　carbon　emission　calculation　method　that　combines　theory　with　practice　is　proposed.　First,　a　theoretical　carbon　emission　model　based　on　the　heat　balance　equation　and　an　actual　carbon　emission　model　based　on　actual　energy　data　are　established,　and　the　key　links　in　the　carbon　emissions　of　asphalt　concrete　are　determined.　Second,　the　carbon　emission　correction　factors　of　five　different　types　of　asphalt　concrete　are　obtained　to　estimate　the　actual　carbon　emissions　more　accurately.　Finally,　the　uncertainty　of　the　parameters　is　evaluated　and　characterized　via　the　DQI-Monte　Carlo　simulation　method.　The　results　show　that　the　carbon　emissions　from　large　to　small　are　modified　asphalt　concrete　(MAC)　＞　ordinary　asphalt　concrete　(AC)　＞　stone　matrix　asphalt　(SMA)　＞　recycled　asphalt　concrete　(ZAC)　＞　warm　mix　asphalt　concrete　(WAC).　The　aggregate　heating　stage　is　the　key　link　in　the　carbon　emission　of　asphalt　concrete.　Controlling　the　aggregate　heating　temperature　and　moisture　content　is　the　most　direct　and　efficient　energy　savings　and　emission　reduction　measure.　©　2024　Elsevier　Ltd
