CONSTRUCTION METHOD OF WATER RETENTIVE PAVEMENT
To provide a construction method for a cast-in-place water-retentive pavement capable of being constructed with little labor in a short time.SOLUTION: A method for constructing the cast-in-place water retentive pavement comprises the steps of: (A) a steps of leveling a water retentive cement milk on a roadbed, (B) a step of placing a porous concrete so that a part (lower part) of the porous concrete is immersed in the water retentive cement milk, (C) compacting, leveling, and then curing porous concrete; in porous concrete, a unit amount of cement is 125 - 950 kg/m3, a unit amount of fine aggregate is 40 - 350 kg/m3, a unit amount of coarse aggregate is 1100 to 2100 kg/m3, and a unit amount of water is 20 -180 kg/m3, a unit amount of thickener or non-separating admixture in water is 0.5-6.0 kg/m3, and a blending amount of high-performance water-reducing agent or high-performance AE-water-reducing agent is 1.7-6.0 mass% to cement.SELECTED DRAWING: Figure 1
【課題】短時間で少ない労力で施工ができる現場打ち保水性舗装の施工方法を提供する。【解決手段】（Ａ）路盤上に保水性セメントミルクを敷き均す工程、（Ｂ）ポーラスコンクリートの一部（下部）が、前記保水性セメントミルクに浸されるようにポーラスコンクリートを打設する工程、（Ｃ）ポーラスコンクリートを締固めて敷き均した後、養生する工程、を含む現場打ち保水性舗装の施工方法であって、ポーラスコンクリートが、セメントの単位量が１２５〜９５０ｋｇ／ｍ３、細骨材の単位量が４０〜３５０ｋｇ／ｍ３、粗骨材の単位量が１１００〜２１００ｋｇ／ｍ３、水の単位量が２０〜１８０ｋｇ／ｍ３、増粘剤又は水中不分離性混和剤の単位量が０．５〜６．０ｋｇ／ｍ３、および高性能減水剤又は高性能ＡＥ減水剤の配合量がセメントに対して１．７〜６．０質量％である。【選択図】図１
