    • PROBLEM TO BE SOLVED: To provide a pavement structure easy to walk on, matching with the environment, and excellent in workability and economic efficiency, using wood materials made of crushed tree core materials or barks. SOLUTION: Over a ground 1 leveled and compacted, is laid the mixed layer 2 of wood materials made of crushed tree core materials or barks, sands with adjusted grain size distribution, and dry and powdered clay, preferably bentnite. The work method for preparing the mixed layer 2 is that wood materials, sands and powdered clay are laid over the ground 1 in this order, then they are mixed and agitated and then rolled by a roller while sprinkling water in order to obtain a flat pavement surface with moderate hardness. This work execution method is simple and can cut off the construction period and cost. The pavement surface can have moderate hardness for easy walk or running if sands are mixed in the wood materials, and further a soft and stable mixed layer can be obtained if clay is added in the layer for ensuring its moderate water retaining capacity and adhesion among the wood materials.

    • 要解决的问题:使用由破碎的树芯材料或树皮制成的木材,提供易于行走的路面结构,与环境相匹配,加工性和经济效益优异。 解决方案:在地面1平整和压实的地方,铺设由破碎的树芯材料或树皮制成的木材材料的混合层2,具有调整的粒度分布的砂子,以及干燥和粉末状的粘土,优选是褐煤。 制备混合层2的工作方法是将木材,砂和粉状粘土依次放置在地面1上,然后将它们混合并搅拌,然后通过辊子滚动,同时洒水以获得平的路面 表面硬度适中。 这项工作执行方式简单,可以切断施工期和成本。 如果在木材中混合沙子,路面可以具有适度的硬度,以便于散步或运行,如果在层中添加粘土以确保其中等的保水能力和粘合力,则可以获得柔软和稳定的混合层 木材。 版权所有(C)2005,JPO&NCIPI

    • PROBLEM TO BE SOLVED: To provide mixed soil for forming a surface layer of clay ground having good water retentivity and water permeability. SOLUTION: The mixed soil is a mixture of fibrous conifer bark obtained by cutting conifer bark, recycled stones obtained by adding cement to construction sludge such as bentonite and hardening the same, and earth and sand. The mean fiber length of the fibrous conifer bark is preferably set to 20 mm or less. The mean particle size of the recycled stone is preferably set to 6 mm or less, and the mean particle size of earth and sand is preferably set to 5 mm or less. The proportion of the mixed soil satisfies the following relationships. The fibrous conifer bark takes up 20 to 40 mass%, the recycled stones take up 10 to 30 mass%, and the earth and soil take up the remaining portion. To form the clay ground by using the mixed soil, first a substrate layer is formed by laying and leveling recycled rubble having a mean particle size larger than that of the recycled stones, and then the surface layer is formed by laying and leveling the mixed soil on the substrate layer. Thereafter surface finishing may be performed if desired. COPYRIGHT: (C)2005,JPO&NCIPI
    • 要解决的问题:提供用于形成具有良好保水性和透水性的粘土地面的表层的混合土壤。

      解决方案:混合土壤是通过切割针叶树皮获得的纤维针叶树皮混合物,通过将水泥添加到建筑污泥如膨润土中并使其硬化而获得的再生石,以及砂土。 纤维针叶树皮的平均纤维长度优选设定为20mm以下。 再生石的平均粒径优选设定为6mm以下,优选将砂土的平均粒径设定为5mm以下。 混合土壤的比例满足以下关系。 纤维针叶树皮占20〜40质量%,再生石头占10〜30质量%,土壤占据剩余部分。 为了通过使用混合土来形成粘土,首先通过铺设和调平平均粒径大于再循环石块的回收瓦砾来形成基底层,然后通过铺设和调平混合土而形成表面层 在衬底层上。 此后,如果需要,可以进行表面精加工。 版权所有(C)2005,JPO&NCIPI
