A paving block with a rubber piece made from, e.g., a used tire, for reducing echoes, noise, wear, icing on the block surface, adhering force of ice, shocks in collisions, etc. The block having high dimensional accuracy and comprising strong rubber piece that does not peel away for a log period is provided by a simple and low-cost method. The method is applied to provide diverse construction blocks to which materials, other than rubber, with various characteristics are attached. A square piece of rubber is cut off from a tire with non-uniform, uneven thickness caused by wear. This piece of rubber is made a surface layer piece (1) of a block, and asphalt that functions as a bonding portion (2) is applied to the back side of the surface layer piece (1). Concrete is placed directly on the asphalt as a curing body (3). The concrete placement thickness is adjusted so that the entire block has a predetermined thickness, and the concrete is cured. Using a holding arm (7), a net-like member (5), a separator (33), a joint (34), etc. can increase the strength of the block.
