Phenol-cresol-formaldehyde resins (PhCR-F) were obtained via polycondensation of a
mixture of phenols (“raw” phenols) obtained from the phenolic fraction of coal tar. PhCR-F …

The main reasons and ways of bitumen modification by polymers were examined. Positive
and negative aspects of the usage of different polymer modifiers (elastomers, thermoplastic …

In this study, the phenol-cresol-formaldehyde (PhCR-F) resin was synthesised from the
phenolic fraction of coal tar resin and formaldehyde through polycondensation. The physico …

Slow-breaking monophase cationic bitumen emulsions have been produced on the basis of
bitumen modified with phenol-cresol-formaldehyde resin (PhCR-F). Bitumen emulsions …

1The 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 …

To obtain modified bitumen with excellent adhesive properties, coumarone-indene resin
(CIR) was used. However, bitumens modified by CIR have somewhat worse plastic …

1 In the presence of various catalysts (TiCl4, AlCl3, H2SO4), the process of obtaining a
coumarone-indene-carbazole resin (CICR), which is produced from liquid products of coal …

The introduction of new road-building materials with advanced physical and mechanical
properties is the trend in contemporary civil engineering, which aims to increase the quality …

Modifiers are added to road bitumens to enhance their properties. The only significant
disadvantage of current industrial modifiers is their relatively high cost. The authors develop …

The chemical modification of oxidized bitumen BND 70/100 by formaldehyde, or rather its
aqueous solution, formalin, was carried out for use in hot asphalt pavement technologies …
