Designed for producing road, roofing, and construction bitumens at oil refineries.
Main advantages:
- Reduces production costs
- Enables the production of various grades and types of bitumen (road, roofing, construction)
- Compared to similar grades of oxidized road bitumen, the compounded samples exhibit 15-40% higher ductility (above 100-120 cm) and 10-15% better adhesion to mineral materials
- The technology is low-waste and features simple equipment design
Brief technology description
The technology for producing high-quality compounded bitumens involves the stages of deep vacuum distillation of fuel oil, further oxidation of the resulting vacuum residue, and its mixing with non-oxidized vacuum residue in specific ratios.

Development stage
The developed technology is used in the production of road and roofing bitumens at the oil refinery in the city of Novopolotsk.
A mathematical model has been developed to control the production process of compounded bitumens.
Patent protection
The technology for producing compounded road bitumen is protected by a patent of the Republic of Belarus.
