What type of concrete deck has panels cast and cured offsite and reinforced with mild steel?

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

Answer: (B)

This question tests how deck construction methods are distinguished by where the panels are made and how they are reinforced. A precast conventionally reinforced deck uses panels that are cast and cured offsite, then transported and installed on the bridge. These panels are reinforced with ordinary reinforcing steel (mild steel rebar), not prestressing strands. After placement, a cast-in-place topping may be added to complete the deck surface, but the structural reinforcement inside the panels is conventional. This matches the description precisely: offsite-cast panels with conventional reinforcement. The other options involve prestressing (PS) or post-tensioning, or a monolithic in-situ pour, which would not be described as panel-based with conventional rebar.
