Global warming impact assessment of asphalt pavement by integrating temporal aspects: A dynamic life cycle assessment perspective

With the increasing severity of global warming, “low-carbon” development is being vigorously promoted. As the largest energy consumer in the transportation industry, road transportation must focus on energy saving and emission reduction. The traditional life cycle assessment (LCA) method conducts pavement environmental impact assessments with limited consideration of dynamic aspects in the time dimension. This study explores certain time-varying factors (traffic volume, vehicle type, pavement roughness, maintenance timing, material recycling rate, electricity mix, and characterization factors) and systematically establishes a dynamic LCA model for asphalt pavements. The proposed model is validated by a case study on an expressway and results show that global warming impact of asphalt pavements is overestimated if dynamic aspects are not considered. Furthermore, preventive maintenance demonstrates higher environmental benefits than regular maintenance. This study provides an operable dynamic assessment model for global warming impact assessment of asphalt pavements.
