摘要

地聚合物技术在道路维护和维修中的迅速应用为减少建筑行业的碳排放提供了一个重要的机会。本研究采用全生命周期评价（LCA）方法，以中国典型公路为例，对地聚合物注浆技术的CO2排放进行评价。LCA跨越了关键的生命周期阶段，包括原材料开采、运输、建设和交通延迟影响。一项与传统水泥基修复方法的对比分析显示，使用地聚合物技术的道路每公里的二氧化碳排放量减少了46.9%。确定施工阶段和缓解交通中断是这一减排的主要贡献者。研究结果提倡采用地聚合物技术作为道路养护的可持续低碳解决方案，强调在环境影响评估中考虑全生命周期的重要性。这项研究为交通运输行业的利益相关者提供了可操作的见解，指导行业走向可持续维护实践，并为建筑行业的整体碳足迹减少做出贡献。与全球可持续发展目标一致，该研究提供了一种实用的方法来提高道路养护项目的环境绩效，倡导采用地聚合物技术。

Advancing toward a low-carbon infrastructure: Emission reduction potential of geopolymer road maintenance

The burgeoning application of geopolymer technology in road maintenance and repair presents a significant opportunity to mitigate carbon emissions within the construction sector. This study conducted a comprehensive life cycle assessment (LCA) to evaluate the CO₂ emissions associated with geopolymer grouting technology, using a typical Chinese highway case study. The LCA spanned key life cycle stages, including raw material extraction, transportation, construction, and traffic delay impacts. A comparative analysis with traditional cement-based repair methods revealed a substantial 46.9 % reduction in CO₂ emissions per kilometer of road maintained using geopolymer technology. The construction phase and traffic disruption mitigation were identified as the primary contributors to this emission reduction. The findings advocate for the adoption of geopolymer technology as a sustainable, low-carbon solution in road maintenance, emphasizing the importance of full life cycle consideration in environmental impact assessments. This research provides actionable insights for transportation sector stakeholders, guiding the industry towards sustainable maintenance practices and contributing to the construction industry's overall carbon footprint reduction. Aligning with global sustainability goals, the study offers a pragmatic approach to enhance the environmental performance of road maintenance projects, advocating for the adoption of geopolymer technology.
