A comparison of the ability of modifiers of different classes to slow down the aging processes occurring in petroleum bitumen during pavement operation is presented in the article. Oxidized and residual road bitumens were used as research objects. Determination of resistance to hardening under the influence of heat and air was performed by the RTFOT method. Samples of oxidized bitumen with the addition of petroleum polymer resins with hydroxyl functional groups and heavy pyrolysis resin were found to have the best resistance, while for residual bitumen the highest resistance was observed with the introduction of heavy pyrolysis resin and sulfur.
