ABSTRACT:
A recreational ramp suitable for use with wheeled vehicles, including a support structure and a molded concrete layer mounted on the support structure. The layer includes a sloping region that extends from a ground level to an above-ground level. Also, a process for the fabrication of a molded concrete layer for such a recreational ramp. The process includes preparing a mold from complementary parts, closing the parts onto one another, thus defining an interior space representative of a concrete layer, pouring concrete mixture into the mold; allowing the concrete to settle and separating the complementary parts of the mold to expose the molded concrete layer. Embodiments of the invention offer the advantages of conventional concrete, i.e., a smooth, quiet and durable surface for riding, while the ramp as a whole remains lightweight and less bulky as compared with conventional concrete ramps. A particularly advantageous embodiment uses self-leveling concrete.
