【発明の属する技術分野】本発明は、木質材料を使用し
た遊歩道や広場、馬場などの舗装技術に関する。BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a technique for paving a promenade, a plaza, a track, or the like using a woody material.

護が叫ばれている昨今、成長が遅く植林・伐採の長期計
画を要する木材の多用は厳に慎まねばならず、木質材料
系舗装も例外ではない。At present, pavements using wood chips are frequently used as promenades in natural parks and the like. However, in recent years, the need to protect forests has been called out for environmental problems at the global level, and heavy use of timber, which is slow to grow and requires long-term planning of tree planting and logging, must be strictly avoided, and wood-based pavement is no exception.

る。[0003] In addition, in the case of wood-based pavement, if the drainage is poor, the wood is corroded quickly, and the service life is shortened accordingly. Shorter service life results in faster rebuilding cycles, leading to wasted wood.
【０００４】そこで本発明では、木材の浪費を抑えられ

を使用可能である。According to the present invention, there is provided a wood-based pavement comprising a subbase on a subgrade, a concrete base layer on the subbase, and a bamboo surface layer on the concrete base layer. As the bamboo material surface layer, a chip-shaped (square), fiber-shaped, or powder-shaped bamboo material can be mixed with a binder, and among them, a fiber-shaped bamboo material is preferably used. That is, a fiber-like bamboo material is preferable because it can have the highest density when laid as a surface layer. As the binder, moisture-curable urethane resin, water-soluble epoxy resin, water-soluble acrylic resin,
Rubber-containing asphalt emulsions, bleached asphalt emulsions, and the like can be used.

う利点をもつ。If the bamboo is left untreated, it will grow in a short time to form a bamboo thicket, and its rhizome easily enters the surrounding thickets,
They destroy other plants because of their fertility. Therefore, it is essential to preserve the ecosystem through annual thinning. The thinned timber is not particularly useful, and has little use except for bamboo crafts. Therefore, if a large amount of thinned bamboo that is produced every year is used as the surface material of a pavement made of a wooden material, unnecessary materials are used originally, so that waste of wood can be prevented. Bamboo also has the advantage that it is less likely to rot than conventional wood chip materials, and has excellent deodorant properties (especially ammonia), repellent properties against insect pests, and antibacterial properties.

Also, a phosphorescent aggregate or a luminescent aggregate can be mixed into the bamboo surface layer, and a top coat layer can be further provided on the bamboo surface layer. According to this, in the case of luminous aggregate, light is emitted for 6 to 8 hours in daylight storage, and in the case of luminous aggregate, light is emitted by ultraviolet irradiation with black light. And the like. Further, by providing the top coat layer, scattering of the material can be more reliably prevented, and shape collapse can be prevented for a longer time. As a concrete base layer to be laid under such a bamboo surface layer, an asphalt concrete system or a cement concrete system can be used, but it is preferable to combine a cement concrete system having the following excellent drainage properties.

徴とする。That is, according to the present invention, in a wood-based pavement comprising a roadbed on a subgrade, a concrete base layer on the subbase, and a woody surface layer on the concrete baselayer, the concrete base layer is mixed in a weight ratio. 75-85%
A crushed stone, 5-15% fine sand, 5-15% cement-based cement concrete, or
The concrete base layer is composed of 75 to 85% by weight of crushed stone, 5 to 15% of fine sand, 5 to 15% of cement, 0.
It is characterized in that it is a cement concrete system produced from 5 to 1.5% of a hardening material and 0.5 to 1.0% by weight of a retarder with respect to the sum of the cement and the hardening material.

得ることが可能となる。By using a cement-based concrete base layer having such a configuration, the drainage of the base layer can be remarkably improved, so that the wood on the surface layer is hardly rotted and the service life can be improved. Therefore, a synergistic effect can be obtained by combining this with the bamboo surface layer.

The bamboo surface layer 1 is laminated about 20 to 50 mm. The bamboo material surface layer 3 of this example is formed by mixing a fiber-like bamboo material and a water-soluble acrylic resin as a binder. Acrylic resins are preferable because they have better slip resistance and better water permeability than urethane resins in a wet state. The volume mixing ratio of the bamboo material and the binder is 15 to 25% of the binder for 75 to 90% of the bamboo in the case of the powdery bamboo, and 80 to 90% of the bamboo in the case of the chip and fiber bamboo.
