ABSTRACT:
A paving block is provided for forming of paved surfaces comprising a plurality of the block laid in adjacent relationship. The blocks are of a planar configuration having a primary body section with coplanar top and bottom surfaces and a vertical peripheral side wall extending between the top and bottom surfaces. Four main wall elements are included in the peripheral wall with these wall elements disposed in parallel pairs, the pairs being positioned in orthogonal relationship to each other. A fifth wall element is included in the peripheral side wall and is positioned between two adjacent ones of the main wall elements in equiangular relationship to each other. In one version of the paving block, two tongue elements are provided in integrally formed relationship with the primary body section and project a distance laterally therefrom at diametrically opposed corners adjacent the respective main wall elements that are interconnected by the fifth wall element. Each tongue element is shaped in plan view to mechanically interengage with side walls of tongue elements and the fifth wall element of adjacent blocks to form a mechanical interlock of adjacently disposed blocks. A second version of the paving block has a single tongue element shaped in plan view to cooperatively interfit in each of two complementally shaped recesses cooperatively forming the fifth wall element to form a mechanical interlock between adjacently disposed blocks.
