    Resins were synthesized via phenol polycondensation with formaldehyde from the coal coking byproduct, phenol fraction namely. Phenol-cresol-formaldehyde resins were obtained from the fractions b.b.–185 °C (PhCFR- 1) and “raw” phenol obtained from the fraction b.b.–185 °C (PhCFR-2). It was established that the resulting resins may be used as modifiers of road bitumen.
