2. Description of the Related Art In various civil engineering or construction works, for example, paving work is carried out in parks, promenades, walking paths, athletic fields, various passages, and schools and hospitals. In this paving work, an elastic paving material having an elastic paving plate fixed to the upper surface may be used mainly for the purpose of enhancing the feeling of walking and safety. Conventional pavement work using this elastic pavement material is laid by laying the pavement material body such as bricks, concrete blocks (or mortar blocks) on the ground surface such as road surface, concrete surface, gravel surface, At the construction site, an elastic pavement plate obtained by press-molding a raw material material in which a crushed piece of rubber is mixed with an adhesive agent into a plate shape was fixed to the upper surface of the main body of the pavement material with the adhesive agent.

In this pavement construction method, since the elastic pavement plate is fixed to the upper surface of the main body of the pavement material with an adhesive agent, a lot of labor (time) is required for the adhering operation and a large amount of the adhesive agent is required. There is a defect. In addition, since the raw material powder adheres to the upper surface of the brick or concrete block, the raw material powder is removed, and at the same time, if the upper surface of the brick or the like is not damaged to some extent, the elastic pavement board is attached to the upper surface of the brick or the like. Can not be glued. In addition to these, before the elastic pavement plate is bonded to the upper surface of the pavement material main body, this pavement material main body must be laid accurately along all the left, right, front and rear directions. It takes a lot of work. If any of the paving material bodies are not laid correctly, it will affect the arrangement of the adjacent paving material bodies in order and also the displacement of the elastic paving board adhered to this upper surface. If it occurs, the design as a whole is lost, and in the extreme case, the construction must be redone.
