Abstract:
1. An anti-adhesion agent composition for asphalt, the anti-adhesion agent composition comprising: (A) a copolymer having an average molecular weight of 5,000 to 100,000 and including constitutional units represented by Formulae (1) and (2) below in which a ratio of the constitutional unit represented by Formula (1) to the constitutional unit represented by Formula (2) is 3:7 to 7:3; (B) a surfactant that is at least one selected from a betaine amphoteric surfactant, an amino acid amphoteric surfactant, a polyoxyethylene alkylamine surfactant, an alkanolamide surfactant, and an amine oxide surfactant; and (C) a water-soluble polyhydric alcohol, wherein the anti-adhesion agent composition contains 0.5 to 10 mass % of the copolymer (A), 0.1 to 5 mass % of the surfactant (B), and 85 to 99.4 mass % of the water-soluble polyhydric alcohol (C), where R where Ms independently represent a hydrogen atom, an alkali metal, ammonium, or an organic ammonium.
