SOIL PAVEMENT MATERIAL
PROBLEM TO BE SOLVED: To provide a soil pavement material having quick-hardening properties, excellent frost damage resistance, excellent weed-proofing properties, and a small amount of hexavalent chromium elution, thereby solving such problems occurring when conventional cement-based solidifiers (hardening agents), magnesia-based solidifiers, and calcium aluminate-based slag are used, that hardening requires a long period of time and hardening does not occur at a low temperature resulting in frost damage, that there is a large amount of contraction resulting in cracking, and that a weed-proof effect is low resulting in a large amount of hexavalent chromium elution.SOLUTION: The present invention provides (1) a soil pavement material comprising alumina cement, a latent hydraulic material, and soil, (2) a soil pavement material described in (1) further comprising a calcium component, and (3) a soil pavement material described in (1) or (2) further comprising an alkaline metal component.SELECTED DRAWING: None
【課題】従来のセメント系固化剤（硬化剤）やマグネシア系固化剤、さらにカルシウムアルミネート系スラグを用いた場合、硬化時間が長く、低温時に固まらず凍害を受けてしまうという課題、収縮量が大きくひび割れが生じるという課題や防草効果が低く、六価クロム溶出量が高い課題というがあった。本発明は、速硬性で凍害への抵抗性に優れ、かつ、防草性に優れ、六価クロム溶出量の少ない土壌舗装材料を提供する。【解決手段】（１）アルミナセメントと、潜在水硬性物質と、土壌とを含有する土壌舗装材料。（２）さらに、カルシウム類を含有する（１）の土壌舗装材料。（３）さらに、アルカリ金属類を含有する（１）または（２）に記載の土壌舗装材料【選択図】 なし
