Composite Construction in bridge decks usually refers to the interaction between insitu reinforced concrete and structural steel. Three main economic advantages of composite construction are : For a given span and loading system a smaller depth of beam can be used than for a concrete beam solution, which leads to economies in the approach embankments.
Our decks are available in a range of sizes, shapes and depths as well as different strength and stiffness properties for use with a range of bridge configurations. Lighter weight means faster installation with reduced load on the support structure.
Composites are more durable than pressure-treated timber decking, without the concern of rotting, splintering or termite damage. But they are not mold-resistant and can be broken down by high temperatures. Also, with high UV exposure, composite deck boards are likely to sag and warp with more unpredictability than timber.

Composite Bridges. Home >> Bridge Types Explained >> Composite Beam Bridges 'Composite' means that the steel structure of a bridge is fixed to the concrete structure of the deck so that the steel and concrete act together, so reducing deflections and increasing strength.
Unlike CIP decks, precast concrete decks are made with concrete slabs that are cast elsewhere and delivered to the site of the bridge for construction. Each segment is about 8 to 12 ft long. Precast decks are usually made of pre-stressed concrete to minimize the risk of damage during transportation.
Composite Bridge Decking (BridgeComposites, LLC) State DOT's have expressed a need for corrosion-resistant, light-weight bridge decking for rapid installation on moveable bridges. Over the past several years, the New York State DOT developed a bridge deck that would be well-suited for such an application.

The 5-inch-thick composite deck carried two 35-ton test trucks during a field test, with a self-weight of about 20 psf. The lightweight deck helped improve the load rating of the bridge, which was a priority for the owner.
Bridge Decks. Every bridge features a deck, the actual surface on which traffic runs. The deck’s structure varies based on the bridge’s purpose. A vehicle bridge, for example, requires a much stronger structure than a pedestrian bridge so that it can better withstand the loads it carries when in use.

'Composite' means that the steel structure of a bridge is fixed to the concrete structure of the deck so that the steel and concrete act together, so reducing deflections and increasing strength. This is done using 'shear connectors' fixed to the steel beams and then embedded in the concrete.
