Anti-adhesive agent for asphalt mixtures
Provided is an anti-adhesive agent for asphalt mixtures which does not readily separate at ordinary or low temperatures, even after dilution with water. The anti-adhesive agent comprising: a water-soluble monohydric alcohol (A) that has a boiling point greater than or equal to 150° C. and is liquid at 25° C.; a compound (B) that is represented by Formula (1); and liquid paraffin (C) that has a kinematic viscosity of 1 to 40 mm 2 /s at 40° C., wherein the mass ratios of (A), (B) and (C) are (A) 15 to 35 mass %, (B) 53 to 79 mass % and (C) 6 to 12 mass %. R 1 O-(EO) n —H . . . (1) (In the formula, R 1 is a hydrocarbon group having a branched alkyl group and having 8 to 12 carbon atoms, EO is an oxyethylene group, and n is the average number of moles of oxyethylene groups added, which is 4 to 10.)
