CRUSHED STONE SPLASH PREVENTION MATERIAL
To provide a crushed stone splash prevention material that is light-weight and highly strong and, for example, enhances efficiency of crushed stone removal and recovery work.SOLUTION: A crushed stone splash prevention material includes a plurality of synthetic resin wires and has apertures formed by combining the plurality of synthetic resin wires. The synthetic resin wires have mass per unit projection area of 0.1 to 1.0 g/cm2 and tensile strength of 1000 N or more.SELECTED DRAWING: Figure 1
【課題】軽量かつ高強度であり、たとえば砕石の撤去や復旧作業効率を高めるといった砕石飛散防止材を提供する。【解決手段】複数の合成樹脂製線材を含み、複数の前記合成樹脂製線材が組み合わされて形成された開口部を有し、合成樹脂製線材は、単位投影面積当たりの質量が０．１〜１．０ｇ／ｃｍ2であり、引張強力が１０００Ｎ以上である、砕石飛散防止材。【選択図】図１
