摘要： Block (1) for pavement characterized in that belt-like portions (2) are formed around the entire periphery of the upper surface of the block by cutting off the periphery in such a manner as to be recessed inward, and to form steps between the beltlike portions (2) and the upper surface of the block (1). According to this structure, the upper end portions of adjacent blocks do not come into mutual contact when they push each other, so that the breakage rate of the blocks can be reduced i remarkably.

摘要： The fracture-free paving block (1) comprises a cement block substrate (1-1) and a top solid layer (1-2), and is characterized in that the top layer is selected from a cured cement mortar layer and a tile-like layer firmly bonded to the substrate with cement mortar; the top layer is bonded to the block substrate with lateral margins (2) of 1 to 8 mm wide in horizontal distance (15) from the peripheral edges of the substrate; and the vertical distance (16) from the surface of the top layer to the peripheral edge of the substrate is 5 to 50 mm. The method for producing the paving block (1) having a tile-like top layer comprises applying adhesive cement mortar between the back of the top layer (1-2) and the upper surface of the substrate (1-1); placing the top layer on the substrate with the above-mentioned margins (2) of the substrate surface; and applying vibration and/or pressurization between the top layer and the substrate.
