METHOD FOR MANUFACTURING FILLER, AND FILLER
To manufacture a filler that can control water permeability after filling while ensuring fluidity.SOLUTION: A method for manufacturing a filler containing an additive solution containing a dissolved polymer additive and a granular material comprises a particle size adjustment step of adjusting a particle size of the granular material based on water permeability required of the filler after filling voids, a viscosity acquisition step of acquiring a target viscosity of the additive solution capable of retaining the granular material based on a maximum particle size of the granular material whose particle size has been adjusted, a concentration selection step of selecting the concentration of the additive solution based on the obtained target viscosity, and an addition amount setting step of setting the amount of addition of the additive solution prepared at the selected concentration to the granular material based on a flowable gap ratio of the granular material.SELECTED DRAWING: Figure 1
【課題】流動性を確保しつつ、充填したのちの透水性能を制御可能な充填材を製造することである。【解決手段】高分子添加剤を溶解した添加剤溶液と粒状材とを含む充填材の製造方法であって、空隙を充填したのちの前記充填材に求められる透水性能に基づいて、前記粒状材の粒径を調整する粒径調整工程と、粒径を調整した前記粒状材の最大粒径に基づいて、該粒状材を保持可能な前記添加剤溶液の目標粘度を取得する粘度取得工程と、取得した前記目標粘度に基づいて、前記添加剤溶液の濃度を選定する濃度選定工程と、選定した濃度に作液した前記添加剤溶液の前記粒状材に対する添加量を、前記粒状材の流動可能な間隙比に基づいて設定する添加量設定工程と、を備えることを特徴とする。【選択図】図１
