This work investigates the role of reagents which improve the characteristics of bitumen. Olefins with different molecular masses were used as modifiers. The catalyst for ionic polymerization was sulphuric acid. The best exploitation characteristics were obtained with bitumen modified with 5% a-olefins C20- C26 using a 1% solution of sulphuric acid.
