Abstract: 
The phenol-cresol-formaldehyde resin (PhCR-F) obtained from phenolic fraction of coal tar has been synthesized via the polycondensation method of “raw” phenols with formaldehyde. The modification of road bitumen by this resin was carried out. PhCR-F in different concentrations was found to be effectively used as a modifier of road bitumen. It was shown that PhCR-F is an effective adhesive additive for road bitumen. The structural types of the oxidized and modified bitumen were determined according to the group-chemical composition and calculated criteria.
