The overlay of wearing surface material on top of an existing approach and/or deck overlay to create a more uniform and smooth riding surface is known as what?

• A. Rib
• B. Rigid Frame
• C. Resurfacing
• D. Relief

Answer: (C)

Resurfacing is the process of applying a new wearing surface over an existing deck or approach to create a uniform, smooth riding surface. This typically involves placing a fresh layer of material, such as asphalt concrete or Portland cement concrete, on top of the existing surface (often with a leveling course to even out thickness variations). The goal is to restore ride quality, improve surface uniformity, and extend the deck’s service life without altering the underlying structural system. The other terms refer to different concepts: a rib or rigid frame denotes structural elements or bridge types, while relief isn’t the term used for this surface rehabilitation.
