ABSTRACT:
Paving stones of concrete as well as artificial stone material are provided having a tread surface along the top thereof as well as upright sides which are located between corner points of the stone. The side surfaces are provided with serrations, wavy-shaped contours and irregular groove-ridges up to 8 mm deep retreating toward the stone interior along the upright side walls. Such irregular serrations, wavy-shape contours and irregular groove-ridges are adapted to interengage with corresponding configuration of adjoining stones to anchor the stones against any lateral shifting and displacement during travel of a vehicle in a curve or when making a turn as well as during application of brakes of the vehicle wich would result in a horizontal thrust being transmitted to the stones which otherwise would be caused to shift or dislocate from the smooth contour of the tread surfacing of the stones.
