Description of the Related Art As a pavement for the purpose of obtaining a soft walking feeling, there is a wood pavement in which an elastic binder is added to a wood chip and spread to form a pavement surface. Also, although it is different from the purpose of obtaining the softness, Japanese Patent Application Laid-Open No. Hei 8-81907 discloses a method in which a skin, a core material chip, and a small piece of an elastic material are mixed, an elastic binder is added, and the paving is performed. As a surface, there is a technology of a wooden pavement in which a gap between side edges of a pavement due to drying shrinkage is prevented.

る。The prior art of wood pavement in which an elastic binder is added to such wood chips is as follows.
Since the wood granular chips themselves are hard and the shape of the granular chips tends to be dense in the filled state, there is a problem that the pavement is not so soft and hard as expected. In addition, the technology of wood pavement mixed with elastic material strips gives a feeling of softness to some extent.However, a large number of elastic material strips protrude from the surface and the road surface cannot be smoothed. The protruding portion does not wear out and is not smoothed, but rather has a problem that a small piece of the surface escapes and comes off due to use, and a large number of fine dents are formed in the trace.

In addition, the wood may use not only a core material but also a granular chip composed of an outer skin and a core material, and furthermore, a resin may be applied to a spread surface. Such a wood pavement can be formed on an asphalt mixture, a permeable asphalt mixture, cement concrete or a permeable cement concrete layer or on an existing pavement. Examples of the resin-based binder of the binder include urethane polymer, silicone-based binder, moisture-curable resin such as acrylic urethane resin, epoxy resin, room temperature reaction-type resin such as polyester resin, solvent-based resin such as acrylic resin, Resin emulsions such as acrylic emulsion, vinyl acetate emulsion, petroleum resin emulsion, SBS latex, SBR latex, chloroprene latex, and natural rubber latex. An example of the resin applied to the surface is an acrylic resin, such as a solvent-based acrylic resin, an acrylic urethane resin, or an acrylic resin emulsion. Also,
By mixing sand in the mixture, the voids between the chips are filled, and a more durable wooden pavement can be formed. Any type of sand may be used, but in order not to impair the water permeability of the wooden pavement, a uniform size of 6 is required.
No. sand is good.
