Description
The "Structures Moonshot" project, initiated by National Highways and led by Atkins, Jacobs, and supported by VSL, advances non-destructive testing (NDT) for highway structures, with a focus on post-tensioned bridges and half joints. Launched in late 2022 and continuing until 2024, its vision to revolutionise asset management for vulnerable bridges, enabling better and more efficient data collection, leading to self-monitoring and self-diagnosis for National Highways’ most critical structures.
The project comprises two phases; The first involves testing high Technology Readiness Level (TRL) NDT technologies on bridge sections from the dismantled A14 Huntingdon Viaduct. These are compared with the as-found physical conditions after hydro-demolition. The goal is to evaluate current NDT methodologies, identify areas for improvement, and enhance efficiencies in deployment.
The second phase centers on developing low TRL NDT technologies tailored for post-tensioned bridges. This includes the use of guided wave technology, with the aims of enabling direct tendon deterioration measurements without intrusive inspections.
Through the collaborative efforts involving National Highways, AtkinsRealis, Jacobs, VSL and the NDT supply chain engaged with the project, this work is leading to a better understanding of how we can determine the condition of post-tensioned bridges and half joints. The project will also provide valuable insights for future bridge inspections and structure maintenance works, enabling the development of clear training and guidance on optimal NDT deployment. This in turn will improve our overall asset management practices, ultimately leading to better safety of our structures and those using and maintaining them, and reducing disruption on our road networks.
