摘要：

The　global　warming　of　cement　concrete　pavement　from　raw　material　extraction　to　road　construction　was　analyzed　by　the　method　of　life　cycle　assessment.　The　characterization　results　showed　that　the　procedure　of　producing　material　is　the　most　important　stage　to　emit　greenhouse　gas　and　it　accounts　for　98.5%　of　the　global　warming　potential　that　caused　by　the　material　production　and　construction　stage.　For　the　materials　used　in　different　structure　layers,　surface　layer　is　the　biggest　impact　of　greenhouse　and　accounts　for　68.9%　of　the　total　impact　caused　by　material　used　in　constructing　pavement.　Therefore　in　the　future,　by　using　recycled　materials　or　more　environmental　materials　will　be　a　good　way　to　reduce　environment　impact.　©　(2015)　Trans　Tech　Publications,　Switzerland.
