Abstract
A bisphenol-formaldehyde resin was synthesized using the polycondensation method of bisphenol A with formaldehyde. Road bitumen has been modified with this resin. The possibility of its use as a road petroleum bitumen modifier has been established for different contents of the synthesized resin. It has been established that the introduction of synthesized bisphenol-formaldehyde resin into the composition of bitumen significantly increases its heat resistance. The synthesized resin and modified bitumens were characterized using IR spectroscopy. The change in the composition and properties of the bitumen modified with bisphenol-formaldehyde resin has been described.
