description	To provide a road repairing material which has rapid hardening property, excellent strength development in a short period of time, and good long-term stability.SOLUTION: (1) The road repairing material includes a cement, calcium aluminate having a vitrification rate of 70% or more, a CaO/AlOmolar ratio of 1.5 to 2.3, and a Blaine specific surface area of 3000 cm/g or more, gypsum, alkaline earth metal hydroxide, a plasticizer, a premixed material comprising inorganic fine powder and an aggregate, and a polymer latex. (2) A repairing method is characterized in providing a partition in one bag in which the premixed material and the polymer latex of (1) are separately filled, mixing the premixed material and the polymer latex by removing the partition immediately before using, and filling the material in a repair spot of a road.SELECTED DRAWING: None 【課題】速硬性で短時間の強度発現性に優れ、長期安定性の良好な道路補修材を提供する。【解決手段】（１）セメント、ガラス化率が７０％以上、ＣａＯ／Ａｌ２Ｏ３モル比が１．５〜２．３、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、石膏、アルカリ土類金属水酸化物、可塑剤、無機微粉末及び骨材を含有してなるプレミックス材料、並びに、ポリマーラテックスからなる道路補修材（２）さらに、一つの袋の中に仕切りを設けて、（１）のプレミックス材料とポリマーラテックスを別々に詰め、使用する直前に前記仕切りを外して混合し、道路の補修箇所に充填することを特徴とする補修方法。【選択図】なし
