Recent developments in FRP composite small-medium span bridges

The challenges in replacing small-medium span bridges are often associated with minimising bridge closures, difficult access, and re-using existing substructures. FRP (fibre reinforced polymer) composite bridges provide a solution due to their lightweight nature and ability to be prefabricated into large, easily transportable modular components. Providing cost effective and expedient outcomes for small bridge asset owners and managers, these technological advantages are highlighted in international case studies, where this approach is seeing rapid adoption. Moss Canal Bridge was a 9m span sub-standard concrete road bridge over a canal that was replaced with a GFRP modular decking system to allow re-use of the existing substructure and to minimise expensive canal closures. Bourne Hill Bridge is a 20m span steel footbridge over a railway which was sub-standard due to extensive corrosion. A novel launched GFRP beam design was developed to minimise railway possessions and to overcome very poor access.
