Abstract：

This　paper　focuses　on　the　life　cycle　assessment　(LCA)　of　different　types　of　biochar　modified　bioasphalt　(BMBA)　by　considering　greenhouse　gas　(GHG)　emission　and　environmental　pollution　factors.　Biochar　and　bio-oil　were　obtained　from　two　types　of　biomass　(waste　wood　and　pig　manure).　The　application　of　BMBA　would　not　only　improve　the　efficiency　of　biomass　utilization　but　also　enhance　the　environmental　protection.　Analyses　were　carried　out　by　considering　different　stages　which　stem　from　the　combination　of　material　preparation,　construction,　use,　maintenance,　and　demolition　recovery.　The　GHG　(CO2　equivalent)　and　environmental　pollutants　(volatile　organic　compounds　equivalent,　VOCs)　of　BMBA　were　used　for　life-cycle　inventory　assessment.　The　results　showed　that　three　critical　factors　including　material　preparation　and　demolition　recovery　contribute　to　environmental　impact.　Bioasphalt　species　could　significantly　affect　the　energy　consumption　factor　and　reduce　the　environmental　pollution.　As　biochar　and　bio-oil　contents　increase,　GHG　emissions　decrease　accordingly.　The　results　indicated　that　material　preparation　had　the　biggest　contribution　in　energy　consumption.　The　findings　highlighted　the　significance　of　bioasphalt　species　and　content　on　VOCs　decay　pattern　in　life　cycle　assessment　and　global　warming　potential.　Copyright　©　2020　American　Chemical　Society.
