FIELD: chemistry.
SUBSTANCE: invention relates to a bitumen composition used as plasticiser for rubber mixtures with the following ratio of components in wt %: bitumen 30-70, polymeric petroleum resin 70-30.
EFFECT: improved physical and mechanical properties of the plasticiser by modifying bitumen with polymeric petroleum resins, and improved operational properties of rubber mixtures made from said resins.
