Abstract: A paving block to produce an accurate, smooth upper surface and accurate spacing between joints in which the body of a block is provided with flanges flush with the top surface on two adjacent edges of the square block, and flanges flush with the bottom surface on the remaining two edges of the block, with studs projecting from the body of the block outwardly in the direction of the second flanges but being substantially shorter than the width of the flanges and lying in the rabbet for engagement with the first flanges of similar paving blocks to obtain a uniform spacing between the blocks which is filled with sand or gravel to produce a neat, uniform appearance. The studs may be separate elements driven into the block, or may be reinforcing rods extending completely through the block through the first flanges and projecting outwardly in the rabbet formed by the second flanges.
