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 …
