By protecting concrete pillars with a ready-to-stick wrap developed by Nanyang Technological University, Singapore (NTU Singapore) and JTC, existing structures can be easily repaired and reinforced to extend its lifespan. This new technology is especially useful for urban cities to rehabilitate ageing infrastructure including buildings and bridges
When the New Jersey Department of Transportation (NJDOT) needed to replace aging bridges, they chose a system of large-diameter, fiber-reinforced polymer (FRP) composite pipe pilings that could meet higher energy absorption requirements and protect concrete bridge piers.
The National Academies of Sciences and the Transportation Research Board (TRB) released a consensus study report for the Innovative Bridge Research and Construction Program.
In 2017, the City of London, Ontario launched a $7.9 million project to remove, dismantle and rehabilitate Blackfriars Bridge. The 143-year-old wrought iron bowstring arch-truss structure is Ontario’s oldest working crossing.
Sandisfield, Mass. received a $1 million grant in 2017 to rebuild Rugg Bridge on Route 57 following years of wear and tear. A steel grid/concrete deck weighing 60 pounds per square foot created a dead load that was too heavy for the aged structure.
When the concrete platform at a Billerica, Mass., commuter rail station collapsed in 2015, the Massachusetts Bay Transportation Authority (MBTA) closed its North and South mini-high handicap accessible platforms at its West Natick Station. MBTA needed a high-performance, corrosion-resistant replacement for the structures.
The Arizona Department of Transportation (ADOT) has turned to a space-age technique to repair and strengthen girders on two Interstate 17 bridges in Phoenix.
