AQUEOUS HARD URETHANE CEMENT MATERIAL FOR ROAD SURFACE, ROAD SURFACE CONSTRUCTION METHOD, AND ROAD SURFACE STRUCTURE
To obtain a road surface having durability against repeated vehicle travel, stationary tire steering when parking, and vehicle travel with chains attached during snowfall, and having little hardening shrinkage and excellent weather resistance.SOLUTION: An aqueous hard urethane cement material for road surfaces contains at least a polyol resin, an isocyanate resin, and a hydraulic cement, and the ratio of the aliphatic isocyanate resin to the total isocyanate resin is 0.5 or more in terms of NCO equivalent ratio. A road surface construction method comprises: a water resistant layer forming step of forming a water resistant layer having water resistance on a road surface base; and a protective layer forming step of forming a hard protective layer using the aqueous hard urethane cement material for the road surface of the present invention. A road surface structure comprises the water resistant layer and the hard protective layer.SELECTED DRAWING: None
【課題】繰返しの車両走行や駐車する際のタイヤの据え切り、降雪時のチェーンを装着した車両走行に対する耐久性を有するとともに、硬化収縮が少なく耐候性に優れる路面を得ること。【解決手段】少なくとも、ポリオール樹脂、イソシアネート樹脂及び水硬性セメントを含み、全イソシアネート樹脂に対する脂肪族系イソシアネート樹脂の比率が、ＮＣＯ当量比で、０．５以上である路面用の水性硬質ウレタン系セメント材料。路面下地に、防水性を有する防水層を形成する防水層形成工程と、本発明の路面用の水性硬質ウレタン系セメント材料を用いて硬質保護層を形成する保護層形成工程とを有する路面の施工方法。前記防水層と前記硬質保護層とからなる路面構造。【選択図】なし
