Abstract:Strong, durable concrete is key to resilient, long-lasting transportation infrastructure—especially in the face of climate change. This project explores innovative strategies for predicting and enhancing the service life of concrete in pavement and bridge systems, addressing the pressing need for sustainable transportation infrastructure. As concrete is pivotal to the durability and resilience of such structures, its environmental impact demands urgent attention. This project aims to reduce greenhouse gas emissions throughout their lifecycle by extending the service life of concrete pavements and bridge decks. A significant focus of the research is on the indications of chloride ion penetration in concrete, which is critical in controlling corrosion of steel reinforcing bars and keeping the infrastructure reliable. This project proposes the integration of lightweight aggregates, which have shown promise in improving the impermeability and resistance to chloride ion penetrations, which can occur through external sources such as seawater and de-icing salts. The findings provide the transportation industry with best practices and guidelines for implementing sustainable material choices while optimizing the performance of concrete structures, thereby contributing to more resilient and environmentally friendly practices that keep American infrastructure safe for moving people and goods.
