Bridges are vital parts of our infrastructure, but they come with a high environmental impact. Traditional concrete materials are carbon-intensive, and frequent maintenance adds to their climate footprint. This research explores how we can reduce that impact by designing longer-lasting materials and using smarter tools for planning and assessment.
The project developed a comprehensive framework that brings together three components:
1. Low-carbon Ultra-High-Performance Concrete (UHPC) designed to reduce emissions while maintaining durability,
2. A conceptual framework for AI-assisted damage detection to support timely and efficient maintenance, and
3. Life Cycle Assessment (LCA) to measure the environmental footprint of both the materials and the long-term repair strategies.
Experimental testing and environmental analysis showed that optimized UHPC mixes can reduce embodied carbon by up to 40% compared to conventional concrete. And due to their extended service life, UHPC overlays can reduce overall climate impact by more than 77% over a 100-year period.
This research offers practical insights for making bridge infrastructure more sustainable. It shows that durable materials, smart monitoring, and lifecycle-based planning are key to reducing emissions and ensuring more climate-resilient construction systems.
