Currently,　the　widely　used　snow-melting　and　deicing　methods　cause　damage　to　road　surfaces　and　the　environment.　To　study　the　impact　of　asphalt-pavement　snow-melting　and　deicing　technology　on　the　environment　during　its　life　cycle,　three　different　snow-melting　and　deicing　technologies　were　investigated:　pavement　containing　salt,　cable-heated　pavement,　and　mechanical　ice　removal.　Based　on　the　life-cycle　assessment　method,　the　three　snow-melting　and　deicing　technologies　were　divided　into　five　processes:　raw-material　mining,　mixing,　transportation,　paving　compaction,　and　snow　removal.　The　impact　of　environmental　emissions　over　the　life　cycle　of　the　three　snow-melting　and　deicing　technologies　was　quantified.　Four　environmental　impacts-global-warming　potential　(GWP),　acidification　potential　(AP),　photochemical　ozone　creation　potential　(POCP),　and　human　toxicity　potential　(HTP)-were　considered　to　evaluate　the　environmental　load　of　snow-melting　and　deicing　technology.　The　results　show　that　CO2　emissions　are　the　largest　in　all　stages　of　snow　melting　and　deicing.　The　environmental　loads　of　the　three　snow-melting　and　de-icing　technologies　are　ranked　throughout　the　life　cycle:　GWP＞　HTP＞　AP＞　POCP.　Of　the　four　impact　categories,　GWP　accounts　for　more　than　74%　of　the　environmental　load　of　the　different　snow-melting　and　de-icing　technologies.　To　compare　the　environmental　loads　of　different　snow-melting　and　deicing　technologies,　their　analysis　results　were　normalized.　It　is　concluded　that　the　environmental　load　generated　by　the　cable-heated　pavement　is　the　largest,　while　that　generated　by　the　pavement　containing　salt　is　the　smallest.　©　2024　Chang＇an　University.　All　rights　reserved.
