<p>A paving block has six sides, and a top (10) and a bottom surface (12). Two of the side surfaces (14, 16) are substantially parallel and substantially twice as long as each of the other four side surfaces (18, 20, 22, 24), two surfaces (18, 20) of the said other four side surfaces each making an angle of substantially 120o with one end of each of the longer side surfaces (14, 16) and each other side surface (22, 24) making an angle of substantially 60o with the other end of each of the longer side surfaces (14, 16). In other words, a block according to the invention as seen in plan is of "chevron" shape a shape that could also be termed a squat "V" shape. This is a simple, easily manufactured block, which permits numerous different arrangements to be laid.</p> |
