Which term describes the topmost surface that bears traffic on a deck?

• A. Plan deck
• B. Wearing surface
• C. Nail laminated
• D. Stress laminated

Answer: (B)

The wearing surface is the topmost layer that bears traffic on a deck. It’s the surface exposed to vehicles and pedestrians and is designed to resist wear and provide slip resistance, while protecting the structural deck beneath. In practice, you’ll look for the wearing surface to be the concrete pavement, asphalt, or timber boards that actual traffic contacts; this layer can wear down, crack, or delaminate over time and is often the part you surface or replace during maintenance. The other terms describe construction methods or design aspects rather than the surface that carries traffic. Plan deck refers to the deck’s layout or design plan, nail laminated describes a method of joining wood layers with nails, and stress laminated refers to a laminated deck built under applied stresses.
