What is the maximum cross slope allowed for ramps?

• A. 1.5%
• B. 2.0%
• C. 2.5%
• D. 3.0%

Answer: (B)

The maximum cross slope allowed for ramps is generally set at 2.0%. This standard ensures that the ramp is accessible and usable for individuals with mobility impairments, allowing for safe navigation without excessive slippage or difficulty in maintaining balance. The 2.0% cross slope helps to facilitate water drainage away from the ramp surface while still providing a level of comfort for users. It represents a balance between proper drainage needs and the guidelines established by accessibility standards, such as the Americans with Disabilities Act (ADA).

While some other options may be close, they either exceed the recommended maximum or fall short of providing an appropriate level of accessibility for users.
