S15: Long term performance of FRP replacement components and structures (Year 3)

November 24, 2025

A limited number of existing complete fibre reinforced polymer (FRP) structures and structures with replacement FRP components have been identified on the TMR network. One of the objectives of installing these components is to gain practical understanding of the performance of the FRP material in bridge applications. Consistent with this objective, this project involved a performance review of FRP components and structures in the TMR network. In addition, TMR is interested in assessing the condition of its stockpiled FRP girders (manufactured by Wagners Composite Fibre Technologies (WCFT) and Loc Composites and stored at several Districts) to determine whether it is appropriate to utilise them. This project included a visual inspection of TMR FRP bridges and replacement components and an assessment of the performance of the stockpiled FRP girders through visual inspection and serviceability load testing.
