Abstract:
1. A paving block having interconnected sides for use in the construction of a paved surface for bearing wheeled traffic, said paving block comprising: an upper planar surface and a lower surface spaced from and generally parallel to said upper planar surface, a lateral surface extending between said upper surface and said lower surface on each side of the block, each lateral surface having a planar lower portion and an associated upper tapered planar portion, said planar lower portion lying in a plane generally perpendicular to a plane of said lower surface so that, with the blocks positioned adjacent each other, said lower portions of said lateral surfaces of adjacent blocks abut against each other, said upper tapered portion of each lateral surface having a lower edge which intersects and terminates at an upper edge of its associated lower portion of said lateral surface, a plane of said upper tapered portion intersecting the plane of its associated lower portion oriented in a vertical plane at an angle greater than zero degrees and less than fifteen degrees with respect to the vertical plane so that an upper edge of each upper tapered portion is spaced from and generally parallel to the upper edge of the upper tapered portion of an adjacent paving block, and at least one of said lateral surfaces having at least one channel extending from said bottom surface towards said upper surface, said channel having a width greater than its depth.
