Fibrwrap Construction recently used its Tyfo Fibrwrap composite system in the recent restoration of Miami’s Grove Isle Bridge.
The rehabilitation project included the retrofit of fibre reinforced polymers to the structure's columns, beams and slabs. In addition to Fibrwrap repairs, Fibrwrap Construction tackled concrete restoration and epoxy crack injection to further strengthen and stabilize the bridge.
Manufactured from glass, carbon, aramid and hybrid fabrics, Tyfo Fibrwrap are held together by TYFO polymers. The company's advanced, high-strength fibre products are specially engineered to repair and restore bridges, buildings, piers and pipelines, offering cost-effective, turnkey repair options for many industrial projects.
The repairs of Grove Isle Bridge were deemed necessary by inspection engineers after discovering corrosive damage to the structure's reinforcing steel.
""We've performed over 6,000 structural upgrades and retrofits since 1988,"" says Fibrwrap Construction CEO Heath Carr. ""Using our innovative composite retrofits, it was our goal to restore the strength and integrity of the bridge while limiting interruptions to the flow of Grove Isle employee and tourist traffic.""
Now that Grove Isle Bridge repairs are complete, the bridge's structural health will be monitored over the next year by students and researchers at the Universities of Miami and Cincinnati.
To initiate this innovative new assessment program, wireless sensors were placed at strategic points along the rehabilitated bridge. By recording vibrations, acoustic wave data and concrete alkaline levels, researchers can detect the presence of cracks and deficiencies that may affect the bridge's future durability.
This new emission technology is intended to help bridge owners and transportation departments monitor and predict future structural problems, alerting them to the need for critical repairs and upgrades.
Australian organisations Austrak, Laing O’Rourke and the University of Southern Queensland (USQ) have joined forces to develop polymer composite solutions for bridge transoms in a $10 million project titled Polymer Composite Transoms for Rail Bridge Deck Replacement (CompTrans).
The American Composites Manufacturers Association (ACMA) led a Transportation and Defence Fly-In, 25-26 September 2018, during which ACMA members and staff met with more than 75 congressional offices and several key decision makers from federal agencies.
As the rail sector looks to new technologies to enable it to answer sustainability, performance and cost challenges, applications for pultruded composites are set to grow, according to a new report from the European Pultrusion Technology Association (EPTA). Lightweight, high performance, durable composites offer energy efficient solutions with lower environmental impact and reduced through-life costs in rolling stock and rail infrastructure.
