Zusammenfassung:	To provide a resin composition for coating civil engineering construction that has good workability and can form a cured product having good transparency and water whitening resistance.SOLUTION: Provided is a coating resin composition for civil engineering construction, which is a coating resin composition for civil engineering construction that comprises a polyurethane resin (a) having a polycarbonate structure, a water-based medium (b), and a cross-linking agent (c) reactive with an acidic group or a salt thereof, and satisfies at least one of the following conditions A and B. Condition A: the acid value of the nonvolatile matter in the coating resin composition for civil engineering construction is 5 to 17 mgKOH/g. Condition B: the acid value of polyurethane resin (a) having a polycarbonate structure is 5 to 22 mgKOH/g.SELECTED DRAWING: None 【課題】良好な施工性を有するとともに、良好な透明性及び耐水白化性を有する硬化物を形成することが可能な土木建築コーティング用樹脂組成物を提供すること。【解決手段】ポリカーボネート構造を有するポリウレタン樹脂（ａ）と、水系媒体（ｂ）と、酸性基又はその塩と反応性を有する架橋剤（ｃ）とを含む土木建築用コーティング樹脂組成物であって、下記の条件Ａ及び条件Ｂのうち、少なくとも一方を満たす、土木建築用コーティング樹脂組成物。条件Ａ：土木建築用コーティング樹脂組成物中の不揮発分の酸価が５～１７ｍｇＫＯＨ／ｇである。条件Ｂ：ポリカーボネート構造を有するポリウレタン樹脂（ａ）の酸価が５～２２ｍｇＫＯＨ／ｇである。【選択図】なし
