摘要
A paving slab or a paving element made of natural stone, preferably basalt, columnar basalt, block basalt, slab basalt, diabase material or granite, for a pavement covering consists of a substantially plane upper walking surface (21), a substantially plane lower base surface (22) parallel to the upper walking surface (21), and a number of lateral surfaces (12, 14, 16, 18). To make it possible for such a paving slab or such a paving element to be produced in a simple and reliable manner, for it to be laid to form a composite unit and for the lateral surfaces to have a natural appearance corresponding to natural stone paving, the lateral surfaces are sawn (16, 18) adjoining the lower base surface (22) and, moreover, broken (12, 14) adjoining the upper walking surface (21).
