A substantiated scientific and technological approach to the design of bituminous binders compositions by compounding unoxidized petroleum feedstocks is one of the key drivers in the development and production of technologically and energy-efficient bituminous binders and asphalt concrete with improved properties for a reliable road surface based on them. A targeted approach to the group composition of bituminous dispersions will help to resolve the issue of developing effective, time-stable and reproducible bituminous compositions. Therefore, the purpose of study is to develop compositions of compounded unoxidized bitumen (BKn) grade 50/70 and to evaluate the effectiveness relative to the trademark BND 50/70. In the work, the following products are considered as components of oil refining for subsequent compounding into BKn 50/70 bitumen: tar, fuel oil, deasphalting asphalt. A comprehensive analysis of results demonstrates the possibility of obtaining a technical result from the use of compounding techniques for unoxidized petroleum feedstock, which consists in the formation of a "sol-gel" dispersed binder structure. It is shown that the designed composition of the bituminous binder is characterized by a stable and resistant structure to thermal destruction. Evaluation of the effectiveness of the developed compositions of BCN is carried out by calculating generalized performance criteria for each composition.
