WEED CONTROL MATERIAL AND WEED CONTROL CONSTRUCTION METHOD USING WEED CONTROL MATERIAL
PROBLEM TO BE SOLVED: To provide a weed control construction method which can prevent weed growth in the soil around the planting, secures water supply necessary for the growth of the planting through the rainwater, satisfies both of a sound growth of the planting and a natural landscape as a green space, keeps the grains having moderate mobility during a laying operation in a construction and can prevent the grains from moving after the construction.SOLUTION: Burned crushed stones of the No.6-7 grain size are targeted and the weed control material 1, forming an asphalt layer which covers the whole around the crushed stone grains and has a total weight ratio of 1-3 wt%, is used. Then, a water permeable sheet 4 is laid on soil 5, the weed control material 1 is laid on the sheet 4 in a layer thickness H in which the growth of the weed seed 7 is prevented.SELECTED DRAWING: Figure 2
【課題】植栽周囲の土壌に雑草が生えるのを防止可能とすると共に、植栽の生育にとって必要な雨水による水分の供給を確保し、植栽の健全な生育と緑地としての自然景観とを両立させ、施工時の敷設作業では粒子が適度な移動性を有し且つ施工後には粒子の移動が防止できる防草施工方法を提供する。【解決手段】焼成した６号〜７号の粒度の砕石を対象とし、該砕石の粒子の周囲すべてを被覆して総重量割合１〜３ｗｔ％の範囲のアスファルトの層を形成した防草材１を用いる。そして、土壌５の上に透水性を有するシート４を敷設し、該シート４の上に、前記防草材１を雑草の種子７が発芽しない層厚Ｈに敷設する。【選択図】 図２
