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.

Machine scores (provisional)
The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.
Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
score_only:v0-immature-baseline · verbatim from the scoring run: score_only means the number may rank works, and no category label ships from it
