What type of concrete deck has panels that are cast offsite but do not include a wearing surface when installed?

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

Answer: (A)

The concept tested is how some precast deck systems are finished at the field. Prestressed deck panels are manufactured offsite as precast units and then installed. If they are not supplied with a wearing surface, that final surface is added later in the field as a cast-in-place topping. This combination—precast, prestressed panels installed without a wearing surface, with the final surface applied on site as CIP topping—describes PS deck panels with CIP topping. The other terms describe different aspects (a monolithic deck is poured in one piece, post-tensioned refers to the prestressing method, and generic precast panels may or may not include a field-applied topping), but they don’t capture the specific setup of offsite casting plus a separate in-place wearing surface.
