A composite sketch
Article Abstract:
Lightweight fibre-reinforced polymers are increasingly being used in bridge construction because they provide greater strength than conventional wood, concrete and steel. However, the reduced rigidity of composites means that bridge spans must be shorter. Lawrence Technological University is one of several universities involved in composite bridge research, focusing on the use of carbon fibre-reinforced polymers and reinforcing bars to reinforce concrete decking.

Mix and match
Article Abstract:
The Ford Island Bridge in Hawaii uses a combination of fixed and floating bridge technologies to span a channel of over 4,000 ft. The bridge, built for the U.S. Navy, comprises a fixed, 3,638-ft-long pile-supported fixed bridge and a 930 ft, precast concrete pontoon bridge that opens to allow for the passage of aircraft carriers. The bridge will be completed in early-1998.

Bonded tendon debate
Article Abstract:
The UK Department of Transport banned the use of bonded tendons in bridge construction. The grouted tendons cause corrosion, but the corrosion can be controlled by using fully encapsulated and electrically isolated tendon (EIT) enclosure. Corrosion does not occur in reasonably grouted tendons which do not contain chlorides.
