Which deck component includes a wearing surface comprising bituminous, concrete, serrated steel, and timber?

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

Answer: (D)

The wearing surface is the top layer of the deck that carries traffic and resists wear and weather. It can be made from different materials depending on design and service, including bituminous (asphalt), concrete, serrated steel, or timber. Since the question lists these materials as examples of what the top layer can be, the correct choice is the wearing surface. The other deck terms describe how the deck is constructed or arranged (structural types), not the top surface material itself.
