Description of the Related Art Conventional walkways and stadium structures are made of ascon, concrete, crushed stone, etc., rubber chips, urethane chips, surface materials such as water-permeable asphalt, etc. Ascon, concrete and crushed stone are used as roadbed materials. These roadbed materials are relatively easy to maintain on a daily basis.

に弾性を付与するために表面材の厚みを変更しなければ
ならず、施工コストに難点がある。However, the walking paths and stadiums using these roadbed materials have the following drawbacks. 1) Since the roadbed itself has no water permeability, even if the surface material has water permeability, rainwater collects on the surface material during and after rainfall, and it requires a great deal of cost to maintain the ground. 2) Furthermore, in winter, the surface material contains water and freezes, and the competition must be stopped. In order to prevent this freezing, a great deal of cost and labor is required for ground maintenance such as seating at night and spraying of salts such as calcium chloride. 3) The elasticity of the surface material is insufficient depending on the type of competition, and the thickness of the surface material must be changed to impart elasticity, which is a problem in construction cost.
