Which category includes treatments such as epoxy overlays, high-friction surface treatments, or rubberized asphalt overlays?

• A. Bridge pavement
• B. Asphalt pavement
• C. Specialized surface
• D. Concrete pavement

Answer: (C)

Treatments like epoxy overlays, high-friction surface treatments, and rubberized asphalt overlays are all aimed at changing the surface performance of a bridge deck rather than defining the structural pavement type. They are specialized surface solutions used to address specific needs—such as wear resistance, skid resistance, noise reduction, or crack sealing—on existing decks. Epoxy overlays provide a hard, chemical-resistant layer on concrete; high-friction surface treatments increase skid resistance through a specialized aggregate and binder system; and rubberized asphalt overlays modify the surface texture, durability, and noise characteristics. Because these methods modify surface behavior for particular performance goals rather than representing standard asphalt or concrete deck pavements, they sit in the specialized surface category.
