11 [§ 4.7.6]

A built-up curb ramp typically consists of asphalt or concrete that is poured and shaped into a ramp that runs at a 90-degree angle away from an intact curb down to the roadway.

Built-up curb ramps cannot project into the path of cars. The “path of cars” includes anywhere cars are allowed to drive, including roadways, parking lot driveways, parking spaces, and access aisles.

Built-up curb ramps should have flared sides with a slope of 10 percent or less or have edge protection and handrails on the sides.
