Source: Advanced Infrastructure Technologies Inc., Orono, Maine

A carbon fiber reinforced polymer composite arch tube product—pumped with ready mixed on site and geared to 20–80-ft. span bridges— has landed the American Society of Civil Engineers’ 2011 Charles Pankow Award for Innnovation. Dubbed Bridge-in-a-Backpack, the 12-in. or 15-in. diameter FRP tubes bear 3/8-in. aggregate mixes with superplasticizers dosed to impart self consolidating concrete-level spread characteristics. As superstructure components, the hardened tubes provide what engineers note are corrosion protection and external concrete reinforcement in lieu of conventional rebar.
