INVESTIGATION OF RESISTANCE OF MODIFIED BITUMINES TO TECHNOLOGICAL AGING

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.
