TITLE OF THE INVENTION: PAVING STONE ABSTRACT OF THE DISCLOSURE: 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 rifling up to 8mm deep retreating toward the stone interior along the upright side walls. Such irregular serrations, wavy-shape contours and rifling 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 which 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.
