PROBLEM TO BE SOLVED: To ensure a release inhibiting property equal to or better than that has been attained by a maleated organic compound by providing a release inhibitor consisting of a tall oil fatty acid and/or a tall oil derivative whose acid value is within a specified range. ;SOLUTION: A release inhibitor consists of a tall oil fatty acid and/or a tall oil derivative which has an acid value of 50 to 300 and an iodine value of 200 or below. A binder composition for pavement is prepared by compounding 0.1 to 5 wt.% of the release inhibitor in a binder such as asphalt or the like. The tall oil fatty acid and tall oil derivative are prepared from an oily by-product or the like obtained from a waste liquor at the time of the preparation of pulp, and comprises 80 to 98 wt.% of fatty acids, 0.5 to 11.0 wt.% of resin acids, 1.5 to 10.0 wt.% of non-saponified matters, and the like and have an acid value of 150 to 200 an iodine value of 70 to 150, with unsaturated fatty acids including oleic acid and linoleic acid. The colorable binder composition for pavement comprises 20 to 90 wt.% of a petroleum-based solvent extracted oil, 80 to 20 wt.% of a petroleum resin 0.5 to 10 wt.% of a thermoplastic elastomer, 0.1 to 5 wt.% of a release inhibitor, and the like.;COPYRIGHT: (C)1999,JPO
