Phenol formaldehyde resins were obtained by polycondensation of a mixture of phenols (technical or “raw” phenols) obtained from the phenolic fraction of coal tar. The resulting resin approximately consists of 1/3 of phenol and 2/3 of cresols. The obtained resins were compared with industrial phenol formaldehyde resins, the raw material of which is pure (synthetic) phenol. The possibility of using the obtained resins as modifiers of road petroleum bitumen has been established, especially as adhesive promoters to bitumen. It is shown that the addition of these resins significantly increases the adhesion to the surface of granite rubble and glass. Adhesion to the glass surface increases for PhCR-F from 33 to 87%; for Iditol from 33 to 90% and adhesion to the crushed stone surface for PhCR-F from mark 3 to mark 5; for Iditol from mark 3 to mark 5. This indicates that PhCR-F and Iditol can used as adhesive additives for oil road bitumen
