Abstract: The fracture-free paving block comprises a cement block substrate and a top solid layer, and is characterized in that the top layer is selected from a cured cement mortar layer and tile-like layer firmly bonded to the substrate with cement mortar; the top layer is bonded to the block substrate with lateral margins of 1 to 8 mm wide in horizontal distance from the peripheral edges of the substrate; and the vertical distance from the surface of the top layer to the peripheral edge of the substrate is 5 to 50 mm.

Abstract: 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 (1.sub.5) from the peripheral edges of the substrate: and the vertical distance (1.sub.6) 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.

Abstract: There is provided a novel adhesive-backed tile panel protected by a release sheet. The prefabricated tile panel comprises a substrate sheet composed of a core fabric and a heat-softening-adherent asphalt composition applied to the both surfaces of the fabric; an adhesive layer having convex and concave portions such as stripes of an adhesive not flowable but sticky at an ambient temperature; and tiles arranged regularly and secured to the asphalt composition layer of the substrate sheet. The convex portions and concave portions of the adhesive layer constitute the gaps through which air present between the tile panels and a substrate board can be purged upon installation of the tile panels.
