ABSTRACT:
An interlocking paving stone which has in certain embodiments a twelve-sided main section and an eight-sided tail section, and in certain other embodiments, has a twenty-sided main section and a sixteen-sided tail section, which main and tail sections are integral with each other, coplanar, and symmetrical about a longitudinal plane perpendicular to the paving stone which bisects it into two equal longitudinally extending sections. The relationship of the lengths of the sides to each other and angles they define are such that a large number of different interlocking patterns are possible which exhibit a high degree of interlock along both opposite edges and both opposite ends of the stones.
