PROJECT OVERVIEW


The Western Australian road network still contains many timber bridges comprising Jarrah and Wandoo piles that have been in operation for more than 60 years. Despite their age, these structures are typically sound apart from evidence of localised decay such as splitting, segmenting, loss of diameter, fin, and internal piping at the waterline and/or ground surface. Over the past 20 years, Main Roads has successfully used epoxy fill/injection solutions as a semi-structural solution to mitigate localised deterioration. Based on this work, WARRIP has identified a potential value opportunity to explore further applications in the use of these epoxies as structural solutions for timber piles, specifically the prevalent “necking” problems. The objective of this project is to develop an open-source, commercially available and fit-for-purpose design and rehabilitation solution to extend the service life of existing timber bridges.
