Abstract: Paving system for mechanically paving with irregular paving stones, the paving system comprising a pre-ordering part (3; 10) for pre-ordering a set of irregular paving stones in an ordered configuration suitable for laying and a transferring part (5; 11) for transferring the set of irregular paving stones in the ordered configuration onto a foundation bed (7). The pre-ordering part and/or the transferring part is provided with a plurality of auxiliary guide rails (2; 18) provided for being accommodated in oblong recesses which are provided in the bottom sides of the stones from one lateral side up to another lateral side for overcoming differences in the thickness of the stones. The auxiliary guide rails extend at regular distances from each other, chosen to correspond with the spacing between the recesses, and have a predetermined shape, chosen to be complementary to that of the recesses.

Abstract: The invention relates to a set of paving stones having different thicknesses with respect to each other. At least one oblong recess is provided in the bottom side of each of the paving stones of the set, said oblong recess extending from one lateral side of the stone up to another lateral side, having a continuous cross-section and being provided for accommodating a complementary, regularly shaped carrier onto which the paving stones are to be laid. For each paving stone the/each recess extends into the bottom side of the paving stone up to a predetermined first distance (h) from a tangent plane to the top side, said predetermined first distance (h) being substantially the same for all paving stones of the set. The invention further relates to a method for laying a pavement with these paving stones and a method for producing these paving stones.
