A value indicating the load capacity of a bridge is called?

• A. Laminate
• B. Leveling Course
• C. Load Rating
• D. Lane Loading

Answer: (C)

Understanding how a bridge’s ability to carry loads is expressed is the key idea here. The value that represents a bridge’s load-carrying capability is called the load rating. This rating is obtained from structural analysis and inspections and reflects the maximum safe live load the bridge can carry given its current condition, materials, geometry, and required safety margins. It’s the figure agencies use to set vehicle weight limits and posting, so heavier trucks may be restricted or routed differently if the rating is lower than the design capacity.

Laminate, leveling course, and lane loading describe different things: laminate is a layered material term, leveling course is a pavement construction layer to create a smooth, level surface, and lane loading refers to how loads are distributed across traffic lanes during analysis. They do not denote a single value for the bridge’s load-carrying capacity.
