UHPC in the UK

UHPC in the UK

Abstract

Despite a recent high-profile application at Hammersmith Flyover, adoption of Ultra High Performance Concrete (UHPC) in the UK remains limited. This contrasts with use globally which continues to grow. A state of the art study was undertaken on behalf of Highways England, the government-owned company responsible for operating and maintaining the UK’s Strategic Road Network, with objectives to identify possible applications and benefits of UHPC, barriers to use,and recommendations to promote increased use on Highways England’s infrastructure. Applications for new-build (full components, in-situ connections) and structural enhancement(link slabs, deck overlays, column jacketing) were identified. Highways England owns a wide range of transport infrastructure, including 6800+ concrete bridges, the majority of which are over40 years old. This makes structural rehabilitation an important topic, and provides justification for promoting implementation of UHPC. The absence of UK standards and guidance for design and execution of UHPC is a key barrier to widespread adoption; some other European countries making use of UHPC have some form of published literature. Further issues include lack of experience amongst designers and contractors, limited numbers of UHPC suppliers, and the absence of knowledge and precedent regarding technical approval. Recommendations are made for stimulating use of UHPC in the short term and include preparation of an action plan identifying additional sources of funding (e.g. innovation funds), conducting a whole life cost benefits analysis, and developing a clear approvals process for UHPC. To pave the way for widespread implementation in the longer term, recommendations include sponsorship of pilot projects,engagement with the academic community, and promotion amongst designers and sub-contractors.
