Those who aren’t familiar with bridge building might think of decks as parts of a ship or the area in the backyard where grills are kept. However, in the industry, we know “deck” is a term for the driving surface of a bridge. Whether constructed from concrete, wood, steel, or open grating, decks that form the driving surface of a bridge need to be strong enough for traffic to cross safely. At U.S. Bridge, we provide a full range of sustainable bridge floor and deck solutions to clients throughout the world. Read on to learn more about the types of decks we offer:
Concrete Deck Slab
When it comes to bridge floor and deck products, the concrete deck slab is one of the most popular. Typically between 7 and 9 inches thick, this deck has two layers of steel reinforcing bars to provide strength and durability.
Asphalt
For this deck type, corrugated steel planks, 3, 5 or 7 gauge, are attached to the stringers of the bridge and become a structural component of the structure.. By galvanizing these planks, the flooring is protected against corrosion. With an asphalt overlay, these types of decks provide a long-lasting, economical, driving surface.
Open Grid Steel Deck
If weight constraints are an issue, open grid steel decking is a wonderful option for a bridge floor. It is characterized by whether the grid is filled, or partially-filled with concrete. If concrete is included, a metal pan or form is included near the base or at mid-height of the grid to support the concrete while it cures.
Precast Concrete Panels
One of the most efficient deck types, precast concrete panels can be constructed quickly and easily. Designed and manufactured off site, these panels can be installed one day and driven over the next. Non-shrink grout is mixed and poured in batches on site.
Nail-Laminated Timber Bridge Floor
Ideal for more rustic locations around the country, these timber decks utilize pressure treated lumber to protect against the elements. Additionally, buyers can opt to cover the deck with asphalt if they choose.
