LaHood to see technology behind ‘backpack bridge’

| Monday, August 17, 2009

Secretary Ray LaHood was scheduled to be in Orono, ME, Monday, Aug. 17, to see a laboratory demonstration and get a firsthand look at what its creators are calling “a bridge in a backpack.”

The technology consists of a carbon-fiber fabric that’s unfolded, then inflated into a tube and coated with resin at the job site. Once inflated, the tubes are filled with concrete to produce structural supports for bridges.

Researchers at the University of Maine say the technique, which is suitable for smaller bridges, is faster and cheaper than traditional methods.
