Abstract
This interdisciplinary research project focuses on developing an innovative, minimally invasive strengthening system for aging bridge structures that can be applied during ongoing traffic operations. Combining expertise from engineering, materials science, and digital technologies, the project aims to create a holistic solution for upgrading existing infrastructure with minimal disruption. A central component is the use of post-tensioning as an effective method for enhancing structural performance and extending service life. Complementing this, biomineralization approaches are explored as a means of supporting natural crack stabilization and contributing to the long-term durability of strengthened structures.
The envisioned system is designed to integrate seamlessly into established maintenance workflows and to adapt to various structural configurations, offering a scalable and resource-efficient strategy for diverse bridge types. Digital planning tools, automated support processes, and continuous condition assessment enable reliable long-term performance while reducing environmental impact.
Validated within the CARE*rehab Key Pivot and at the CARE Life-size Bridge Experimentation Site, the project supports the transition toward climate-neutral and resilient infrastructure management. By improving rehabilitation productivity and promoting sustainable strengthening concepts, it contributes to the long-term safety and efficiency of essential transport networks.
