Abstract. Petroleum bitumen is currently widely used in road construction. Currently, bitumen of the 4th generation, that is bitumen modified with polymers, is considered to be the widest industry of bitumen production. They allow to provide a high level of performance indicators, such as: heat resistance, crack resistance, long-term strength, shear resistance and resistance to low-temperature cracking.
It is promising, at the moment, to create bitumen with improved operational properties by introducing high-molecular compounds (polymers and elastoplasts).
The use of PBB is due to the fact that the Russian Federation is located in a harsh climatic zone, which leads to an increase in deformation loads. To ensure long-term and reliable performance of asphalt concrete pavement in such conditions, methods for the development of organic binders were adopted.
This article is written in order to expand the literature review on polymers used in bitumen production to achieve the required grades of bitumen. And also in this article, methods of introducing various polymers into bitumen binders with test results are presented.
