| Abstract | The paper examines the significance of anti-corrosion coating systems for steel bridges within transportation networks, with a particular focus on their long-term sustainability. The study assesses the long-term sustainability of four coating systems, analyzing their performance, cost, and environmental impact over a hypothetical 75-year bridge lifespan. Key considerations include the service life of each coating system, the frequency and extent of maintenance required, the emission of volatile organic compounds (VOCs), and the broader social costs, such as public inconvenience due to maintenance activities. The research presents detailed data, equations for estimating costs, and methodologies for sustainability analysis in varying corrosive environments (C2, C3, and C5). The findings underscore the necessity of selecting low-VOC materials to minimize environmental impact, while also considering the efficacy of corrosion protection and the associated social impacts. This comprehensive approach aims to guide stakeholders in selecting the most sustainable corrosion protection strategies, ensuring relevance in diverse and evolving environmental and societal contexts. |
