Abstract
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 coking, and its subsequent use for bitumen modification was investigated. The influence of the catalyst type on the yield and modifying properties of CICR (change in thermoplastic and adhesive properties of bitumen after adding the obtained resins to them) was studied. The effect of catalyst amount on the resin synthesis and subsequent modification of bitumen with the synthesized product was determined. According to the results, the optimal type and amount of the catalyst for obtaining CICR were chosen. The de-termined optimal amount of coumarone-indene-carbazole resin synthesized using the selected type of catalyst was found to have the most positive effect on the adhesive characteristics of road bitumen
