ROADBED CONSTRUCTION METHOD AND ROADBED STRUCTURE
To provide a roadbed construction method and a roadbed structure capable of maintaining excellent water permeability and water retentivity for a long period of time and forming a roadbed having good maintainability.SOLUTION: A roadbed construction method comprises the steps of: forming a culvert drainage layer 11 on a roadbed G; forming a lower layer 12 on the culvert drainage layer 11; and forming an upper layer 13 on the lower layer 12. The step of forming the lower layer 12 includes a step of placing a mixture formed by mixing and agitating a granite soil, a cement-based solidifying material, a granulating agent, and water on the culvert drainage layer 11 and solidifying the mixture. The step of forming the upper layer 13 includes a step of placing a mixture formed by mixing and agitating a granite soil, a cement-based solidifying material of the amount smaller than when forming the lower layer 12, a granulating agent and water on the lower layer 12 and solidifying the mixture.SELECTED DRAWING: Figure 1
【課題】優れた透水性及び保水性を長期間維持することができ、メンテンナンス性も良好な路盤を形成することができる路盤施工方法及び路盤構造を提供する。【解決手段】路床Ｇ上に暗渠排水層１１を形成する工程と、暗渠排水層１１上に下部層１２を形成する工程と、下部層１２上に上部層１３を形成する工程と、を備え、下部層１２を形成する工程が、真砂土、セメント系固化材、団粒化剤及び水を混合・撹拌して形成された混合物を暗渠排水層１１上に打設して固化させる工程を含み、上部層１３を形成する工程が、真砂土、下部層１２を形成する場合よりも少ない分量のセメント系固化材、団粒化剤及び水を混合・撹拌して形成された混合物を下部層１２上に打設して固化させる工程を含む路盤施工方法である。【選択図】図１
