Which deck panel type includes CIP topping to provide a wearing surface?

• A. PS deck panels with CIP topping
• B. Precast conventionally reinforced
• C. Monolithic
• D. Post-tensioned

Answer: (A)

The key idea is that a cast-in-place (CIP) topping provides the wearing surface. Polystyrene (PS) deck panels combine precast skins with a lightweight core, and a layer of concrete is cast in place on top to create a durable, continuous riding surface. This CIP topping is what gives the deck its final wearing surface and smoothness, tying the precast panels into a full deck. Other deck-panel systems—conventional precast reinforced, monolithic, or post-tensioned—don’t use this on-site topping in the same way, so they don’t rely on a CIP topping for the wearing surface. Therefore, the correct choice is PS deck panels with CIP topping.
