Which category would include epoxy overlays and high-friction surface treatments applied to improve skid resistance and waterproofing?

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

Answer: (A)

The idea being tested is recognizing surface treatments that are applied to enhance performance rather than serving as the standard wearing surface. Epoxy overlays act as a protective, waterproof coating on the bridge deck and can improve durability, while high-friction surface treatments create a textured, skid-resistant layer to reduce slipping in wet conditions. Both are considered specialized surface measures because they’re added on top of the base deck material to achieve specific performance goals like waterproofing and increased friction, rather than representing the primary concrete or asphalt pavement itself. So, this category fits with specialized surface rather than the broader terms for typical bridge or pavement materials.
