Contractors leveling accessible parking stalls often use Portland cement concrete because the pavement elevations can be more precisely set with forms instead of using a paver placing hot mix asphalt concrete. With either material, the slope from the accessible stalls must be gradually tapered to the existing pavement, otherwise a hazard is created. You could imagine a small skate park would be created by having a few of these accessible parking areas located close together. When the adjacent pavement is rehabilitated, these “ramps” will have to be removed, aggregate placed to create a gradual slope, and new, safer pavement paved.
