Superimposed Dead Load is defined as loads that are applied when?

• A. Before concrete deck is hardened
• B. After concrete deck has hardened
• C. During deck curing
• D. Not applicable

Answer: (D)

In bridge loading, there isn’t a standard category called “superimposed dead load” defined by a specific time of application. Dead loads are permanent weights the structure carries, like the deck, beams, and any permanent fixtures. Any additional permanent weight added after construction (such as a finished wearing surface or fixtures installed later) is still treated as dead load, not a separate timing-based category. Because the timing isn’t used to define a distinct load class, the concept isn’t applicable as a separate definition.
