Zusammenfassung:FIELD: chemistry. ^ SUBSTANCE: proposed bitumen modifier contains bitumen, a polymer additive, and a regenerate of rubber products. It also contains masut and/or goudron, organic peroxide (dicumyl peroxide or benzoyl peroxide). It contains polyamide as a polymer additive, and the above mentioned regenerate is obtained from thermo-mechanical degradation in an auger-type dispergator, containing not less than 10% rubber fraction with molecular weight 18000-22000, with the following ratio of components, wt %: bitumen 15-18, polyamide 3-9, goudron and/or masut 15-20, organic peroxide (dicumyl peroxide or benzoyl peroxide) 5-8, and regenerate constitutes the rest. ^ EFFECT: increased elasticity of bitumen with increased adhesion to filler at the same time. ^ 2 cl, 5 ex, 2 tbl
