Coumarone-indene (CIR) and coumarone-indene-carbazole resins (CICR) were obtained by ionic cooligomerization based on fractions extracted from liquid products of coal coking (gasoline fractions and coal tar). CIR and CICR are used as road bitumen modifiers to improve thermal resistance and adhesion. A cheap plasticizer has been selected to be used with CIR to produce polymer-modified bitumen (PMB). The change in the composition and properties of bitumen modified with CIR was described. A method for estimating the change in the adhesion properties of bitumen at low temperatures has been developed, which simulates the behavior of bitumen during the operation of pavements in winter and during sharp changes in weather conditions. The possibility of using the obtained CICR as adhesive enhancers for bitumen has been established. It is shown that the addition of these resins significantly increases the adhesion of bitumen to the surface of granite gravel and glass.
