SOIL PAVEMENT MATERIAL AND SOIL PAVEMENT METHOD
PROBLEM TO BE SOLVED: To provide a soil pavement material, which rapidly hardens and has excellent resistance against freezing damage and restrains growing of grass from cracks resulting from dry shrinkage, and a soil pavement method.SOLUTION: Provided are (1) a soil pavement material containing calcium aluminate, which has 70% or more of vitrification rate, 1.0 to 2.7 of CaO/AlOmole ratio, 15% or less of impurity and 3000 cm/g or more of blaine specific surface area, a shrinkage reducer and/or fiber and soil, (2) the soil pavement material shown in (1), which contains gypsum, (3) the soil pavement material shown in (1) or (2), which further contains calcium silicate, (4) a soil pavement method, which lays any of the soil pavement materials (1) to (3) and sprinkles water to compact the soil pavement material, and (5) the soil pavement method, which mixes and agitates any of the soil pavement materials (1) to (3) and water and lays and compacts the mixed and agitated material.SELECTED DRAWING: None
【課題】速硬性で凍害への抵抗性に優れ、乾燥収縮に伴うひび割れから雑草が生えてくることを抑制する、土壌舗装材料及び土壌舗装方法を提供する。【解決手段】（１）ガラス化率が７０％以上、ＣａＯ／Ａｌ２Ｏ３モル比が１．０〜２．７、不純物が１５％以下、ブレーン比表面積が３０００ｃｍ２／ｇ以上であるカルシウムアルミネートと収縮低減剤及び又は繊維と土壌を含有してなる土壌舗装材料、（２）さらに、石膏を含有してなる（１）の土壌舗装材料、（３）さらに、カルシウムシリケートを含有してなる（１）又は（２）の土壌舗装材料、（４）（１）〜（３）のいずれかの土壌舗装材料を敷設し、水を散水し締め固める土壌舗装方法、（５）（１）〜（３）のいずれかの土壌舗装材料と水を混合攪拌したものを敷設し、締め固める土壌舗装方法、である。【選択図】 なし
