It has been studied the production of petroleum resins by low-temperature inverse emulsion oligomerization of C9 fraction of diesel fuel pyrolysis liquid by-products. It is established that the determining factors of the C9 fraction of the inverse emulsion oligomerization are the following: reaction time, emulsifier concentration and phase ratio.  Yield and physicochemical characteristics of oligomers сorrelations were established.

Slow-breaking monophase cationic bitumen emulsions have been produced on the basis of bitumen modified with phenol-cresol-formaldehyde resin (PhCR-F). Bitumen emulsions were used as a binder for thin-layer coatings with slurry surfacing mixes (SSM). Physical and technical parameters of modified and unmodified emulsions were determined and analyzed. The optimal compositions of SSM were selected according to the breaking criterion. The values of SSM wet track abrasion were determined.

The road slow-setting monophase cationic bitumen emulsions have been prepared from bitumen modified by coumarone-indene resin with epoxy groups. Еmulsions were obtained using a colloid mill at the standard temperatures (413–423 K). The physico-technical parameters of modified monophase emulsions have been established and the comparative analysis with the basе sample has been made.

Hydrocarbon  resins (oligomers) are produced on the basis of fraction C9 of oil refining by-products. The low-temperature emulsion oligomerization can reduce the temperature and duration of the process compared to the existing technologies.
