ABSTRACT:
A paving stone (10) is provided which includes individual sectors (20, 30) of uniform size and shape. Each sector (20, 30) is joined together to form a unique pattern such as a cross-paver (10), a Z-paver (110) or an S-paver (210). Some sectors (20, 30) are tips sectors (20) which attach to only one other central sector (30) and some sectors (20, 30) are central sectors (30) which attach to two or more other top sectors (20). Each of the sectors (20, 30) extend between a common top surface (40) and a bottom surface (50). An outside surface (60) defines a periphery of the paving stone. A V-groove (80) is positioned on the top surface (40) at margins between adjacent sectors (20, 30). The V-groove (80) includes a crease (82) on a bottom thereof which encourages vertical crack propagation from the top surface (40) through to the bottom surface (50) in a plane when a appropriate force-applying tool is utilized. When this occurs the paver (10) is modified into a paver of a different shape. Spacers (66) on the outside surface (60) of the paver (10) provide interstices (90) between adjacent pavers (10).
