Compared　with　normal　rigid　concrete　pavement　overlay,　the　overlay　constructed　with　ultra-high　ductile　engineered　cementitious　composites　(ECC)　has　a　longer　service　life.　Life　cycle　assessment　and　cost　analysis　of　overlayer　made　of　six　typical　ECC　materials　were　carried　out.　The　results　show　that　although　ECC　overlays　do　not　have　short-term　advantages　in　terms　of　environmental　impact　and　cost,　their　long-term　environmental　impact　and　cost　are　significantly　lower　than　those　of　normal　rigid　concrete　overlay　due　to　their　exceptionally　long　service　life　and　lower　maintenance　frequency.　Compared　with　normal　rigid　concrete　overlay,　ECC　overlays　with　supplementary　cementitious　materials　(fly　ash　or　ground　granulated　blast　furnace　slag)　and　environmentally　friendly　fibers　(polypropylene　fiber　or　basalt　fiber)　reduce　the　global　warming　potential　by　63.　2%　~　68.　5%　within　a　life　cycle,　while　their　costs　only　account　for　9.　6%　~　23.　3%　of　normal　concrete　overlay.　©　The　Author(s)　2023.
