This research investigates sustainable construction practices and life cycle assessment (LCA) in repairing and strengthening concrete bridges. The study emphasizes the importance of minimizing environmental impact while maintaining structural integrity and functionality. Sustainable approaches are discussed, and the role of LCA in evaluating and comparing the environmental impact of different repair options is highlighted. Combining these approaches, the research presents a framework for environmentally responsible bridge repair practices that enhance sustainability and performance. The findings underscore the potential for significant environmental benefits by adopting innovative and recycled materials and low-impact repair techniques, all assessed via comprehensive LCA methodologies.
