Which of the following is NOT an acceptable tactile surface for ramps?

In the context of tactile surfaces for ramps, the focus is on ensuring accessibility and safety for individuals with visual impairments. An acceptable tactile surface must provide adequate sensory feedback to help users navigate the ramp safely.

Brushed concrete, grooved concrete, and corduroy surfaces are designed to offer tactile cues that can be felt underfoot. These surfaces typically have texture or patterns that indicate elevation changes or transitions. For instance, corduroy strips can serve as a warning before a ramp begins, alerting users to the change in grade.

Tile, on the other hand, may not consistently provide the same level of tactile feedback as the other options. Many types of tiles can be smooth and slippery, particularly when wet, which could pose safety risks for users who rely on tactile information for navigation. This makes tile an inadequate choice for tactile surfaces on ramps, as it does not fulfill the necessary requirements to alert individuals about the change in slope or surface condition effectively.

Choosing appropriate tactile surfaces is critical in meeting accessibility standards and ensuring all individuals can safely navigate ramps.
