SOIL PAVEMENT MATERIAL
To provide a soil pavement material that is capable of quick hardening, excellent in resistance to freezing damage, reduced in the elution amount of hexavalent chromium, and excellent in weed-preventing effect and crack resistance.SOLUTION: A soil paving material of this invention contains cement, soil, calcium aluminate with a vitrification ratio of 70% or more, a CaO/Al2O3 molar ratio of 1.0 to 2.7, and an impurity content of 15 mass% or less, and an additive; the additive contains a thiosulfate, a sulfite, and boron, and when the content of the thiosulfate in the solid content is X (mass%) and the content of the sulfite is Y (mass%), X and Y satisfy 10≤X/Y≤100.SELECTED DRAWING: None
【課題】速硬性で凍害への抵抗性に優れ、かつさらに六価クロム溶出量が少なく、防草効果、ひび割れ抵抗性に優れる土壌舗装材料を提供する。【解決手段】本発明の土壌舗装材料は、セメントと、土壌と、ガラス化率が７０％以上、ＣａＯ／Ａｌ２Ｏ３モル比が１．０～２．７、不純物含有量が１５質量％以下であるカルシウムアルミネートと、添加剤を含み、その添加剤はチオ硫酸塩と、亜硫酸塩と、ホウ素を含み、かつ、固形分中のチオ硫酸塩の含有量をＸ（質量％）、亜硫酸塩の含有量をＹ（質量％）としたとき、Ｘ，Ｙが、１０≦Ｘ／Ｙ≦１００を満たすものである。【選択図】 なし
