A small precast-concrete bridge in New Jersey is being replaced with a hybrid-composite beam structure that could have a service life of 100 years. This is the third project using the technology, which combines a glass-fiber reinforced shell, self-consolidating concrete for compression reinforcement and high-strength continuous steel fibers for tension reinforcement.
HC Bridge Co. LLC, Chicago, is supplying beams for the $1.34-million state Rte. 23 Peckman’s Brook Bridge in Cedar Grove, N.J. The 50-year-old four- lane, 66-ft-wide, 30-ft-long bridge is considered structurally deficient and is being replaced with composite beams manufactured by Harbor Technologies LLC, Brunswick, Maine. The first stage, consisting of six beams, was installed by Ritacco Construction Inc., Belleville, N.J., using only an excavator.
