ABSTRACT:
A paving block that closely resembles a used mined cobblestone. The blocks are manufactured by a bi-layer concept that is subjected to processes that cause the layers to structurally integrate. The process and composition permit the mass production of blocks having independent top topographies that emulate the surfaces of original cobblestones and with a comparable strength.
