The article provides an expert analytical review of domestic and foreign literary sources based on the tasks set to achieve the goal of developing innovative technologies for producing high-quality bitumen from by-products of oil production and processing. Modern scientific work demonstrates the effectiveness of using polymer, mineral and biological components, as well as recycled materials to increase the durability and stability of bitumen binders. Particular attention is paid to polymer modifiers such as SBS (styrene-butadiene-styrene), which increase the elasticity and strength of bitumen, reducing the likelihood of cracking and deformation. The use of recycled materials, including rubber chips, vacuum gas oil and fly ash, not only improves the properties of bitumen, but also reduces the negative impact on the environment. A promising area is the use of biomodifiers, among which lignin, a natural polymer with high chemical and thermal stability, plays a special role. Studies have shown that the introduction of lignin into bitumen improves its rheological properties, increases resistance to aging and oxidation, and increases the rigidity and strength of the coating. Lignin can act as a filler or partial replacement for bitumen, which makes it an environmentally and economically beneficial component. The use of various modifying additives, including polymers, industrial waste and biocomponents, contributes to improving the quality of bitumen, reducing production costs, increasing the energy efficiency of technological processes and extending the service life of road surfaces. It is also important to evaluate the change in bitumen properties during the production and laying of asphalt concrete mix.
