Abstract
A hollow paving block comprises a substantially planar member having a first surface and a second surface opposite the first surface. The first surface of the planar member is a textured surface which functions as a top of the paving block. A side wall extends along and away from a periphery of the second surface of the planar member to define a cavity in the paving block. The side wall has a beveled edge which extends about a mouth of the cavity. At least one protrusion extends along the second surface of the planar member. The paving block is formed in part from crumb rubber and polyolefin.
