Pertains to the combination of structural elements that assemble the surface or roadway of a bridge.

• A. Bridge deck system
• B. Bridge deck
• C. Roadway system
• D. Deck slab

Answer: (A)

The term that best fits is the bridge deck system. This naming reflects the whole assembled surface that carries traffic and transfers loads to the supporting structure, including the concrete deck (slab), any wearing surface or overlay, reinforcement, edge elements, joints, drainage, and the way it connects to girders or other substructure components. The deck itself refers only to the concrete slab portion, not the full set of components that form the surface. The roadway system is a broader term that can imply general road infrastructure beyond the bridge surface assembly. So, the complete surface assembly on a bridge is properly called the bridge deck system.
