CEMENT-BASED POROUS PAVING MATERIAL
To provide a cement-based porous paving composition, which is excellent in water-permeability, fluidity resistance, aggregate scattering resistance, adhesion and workability, and capable of early using for traffic.SOLUTION: A cement-based porous paving composition comprises, as a constituent material, cement, aggregates A in which a proportion of aggregates having a particle size of 2.5 mm or less is 80% by mass or more, aggregates B in which a proportion of aggregates having a particle size of 3-7 mm is 80% by mass or more, and a polymer emulsion for mixing cement. In cement-based porous paving composition, a mass ratio (polymer/cement) of the polymer and the cement contained in the polymer emulsion for cement mixing is from 0.12-0.80. A cement-based porous paving material for preparing the cement-based porous paving composition includes the aggregates B, the polymer emulsion, and a combination of granular materials including the constituent material other than the polymer emulsion and the aggregates B.SELECTED DRAWING: None
【課題】交通の早期開放が可能であり、透水性、耐流動性、耐骨材飛散性、付着性及び施工性に優れたセメント系ポーラス舗装用組成物を提供する。【解決手段】セメント、粒度が２．５ｍｍ以下である骨材の割合が８０質量％以上である骨材Ａ、粒度が３〜７ｍｍである骨材の割合が８０質量％以上である骨材Ｂ、及びセメント混和用ポリマーエマルションを構成材料として含むセメント系ポーラス舗装用組成物であって、セメント混和用ポリマーエマルションに含まれるポリマーとセメントの質量比（ポリマー／セメント）が、０．１２〜０．８０であるセメント系ポーラス舗装用組成物。該セメント系ポーラス舗装用組成物を調製するためのセメント系ポーラス舗装用資材であって、該資材が、上記骨材Ｂと、上記ポリマーエマルションと、上記ポリマーエマルションと上記骨材Ｂ以外の上記構成材料を含む粉粒状物の組み合わせからなるセメント系ポーラス舗装用資材。【選択図】なし
