FIELD: petroleum product-based materials. SUBSTANCE: bitumen composition appropriate for use in road building, manufacture of roofing, waterproofing, and sealing materials contains, wt %: bitumen 81.0-97.5, butadiene/styrene copolymer 1.0-14.0, adhesion additive 0.5-5.0, and optionally triethanolamine or polyethylenepolyamine, 0.25-2.0 wt parts per 1 wt part adhesion additive. The latter is maleic anhydridemodified low-molecular polybutadiene with bound maleic anhydride content 12-21% and having dynamic viscosity 10-100 Pa.s (25 C). EFFECT: preserved high adhesion properties of bitumen composition at insignificant dosages of adhesion additive, improved physico-mechanical characteristics, and enlarged assortment of adhesion additives. 2 cl, 2 tbl, 7 ex
