Adding 50 Years of Service Life to Victoria’s Lerderderg Bridge
Located between Melbourne and Ballart, the Lerderderg Bridge is a key piece of Victorian infrastructure, consisting of two bridges, totalling four lanes of traffic. As part of the Major Highway Upgrade Project by the Department of Transport (VicRoads), a range of Master Builders Solutions products were specified to increase the load-carrying capacity and extend the design life of the bridge by more than 50 years.
VicRoads utilised four MasterBrace products during the rehabilitation works:
MasterBrace Laminate: Long 100mm wide strips of carbon laminate, bonded to the I-beams to increase the general load-bearing capacity in flexure.
: 50cm wide carbon fibre sheet used to wrap the underside of the bridge to increase the shear strength.
: Pultruded carbon fibre rods, embedded into the bridge deck, providing increased tensile str ength over the piers.
: A two-pack, thixotropic epoxy structural adhesive used to bond the products mentioned above to the concrete surfaces of the bridge.
As each bridge consists of two lanes, traffic was able to continue
flowing in both directions while repairs were made to either bridge. To find
