AltusGroup Says Says New CarbonCast Piles Extend Bridge Lifespans
The company says reinforced polymers help improve corrosion resistance
A new innovation by AltusGroup could reportedly reduce maintenance costs and extend the lifespan of bridges from 50 years to upwards of 75 to 100 years by improving their corrosion resistance through the use of carbon fiber reinforced polymer (CFRP) grid in precast concrete bridge piles.
In this technology, CFRP mesh surrounding a composite support structure with a plurality of support strands is encapsulated in concrete to provide high corrosive resistance and provide increased ability to withstand compressive, tensile and shear loading as compared with carbon steel spirals commonly used in piles today.
