ABSTRACT PAVING BLOCK ARRANGEMENT FOR LAYING A PAVING-SET ARC ASSEMBLY An arcuate paving block assembly comprising two outer transitional blocks (1) with four arcuate sides, wherein two adjacent sides (10, 18) are curved inwards and the other two sides (19, 20) are curved outwards in order to form a continuous transition from one arc to another; adjacent thereto on both sides an equal number of arc blocks (2, 3, 4; 2a, 3a, 4a) constructed to be mirror images of each other and symmetrical or mirror image shaped keystones of apex blocks (5, 6, 5a, 6a; 7, 7a, 8) which together make up the entire length of an arc, the whole being such that when laid the two outer edges (10) of the transitional blocks (1) enclose an angle of 90° and the height (H) of all the blocks measured at right angles to an imaginary baseline (S) through the lower corner of the transitional blocks (1) is the same. Herein the blocks have a lower portion remote from the top tread surface which extends further in the horizontal direction and an upper portion of less extent in the horizontal direction, wherein the lower portion of the radial sides (21) of the arc blocks and crown blocks and the outwardly curved sides (19, 20) of the transitional blocks (1) are provided with vertical or perpendicular projections (14, 15) and the edging of the upper portion has lateral surfaces which are irregularly formed in the same way as a natural stone.
