Abstract (en)
[origin: EP0224048A2] 1. Interlocking paving element, in particular made of concrete, for wheel tracks, having the following features : a) the abutting surfaces running transversely to the track direction have a curvature for forming essentially circular-arc-shaped joints, b) the convex abutting surface has a groove and the concave abutting surface a tongue, c) the cross-sectional boundaries (16, 17) of groove (15) and tongue (14) are curved in a force-transmission zone (K) and, on either side of the force-transmission zone, have a transition section of opposite curvature, in such a way that, in the joint (18) between adjacent elements (11) of the same the laid in the interlocking arrangement on an elastic bedding (10), elastic restraint (9) results which permits a difference in inclination between the adjacent elements, which difference in inclination increases as the forces to be transmitted increase.
