This article discusses the ways and methods of modifying bitumen with crumb rubber obtained from used recycled car tires. A method for modifying bitumen with crumb rubber in a two-stage technological process is proposed. The main modifiers are considered, the analysis of data from literature sources on the modification of bitumen with polymers to improve the physical and mechanical properties is given. Own research data on the modification of bitumen with crumb rubber are presented. The main conclusions are made, the analysis of the results obtained, and recommendations are made for the further use of bitumen modified with crumb rubber in a two-stage technological process.

Keywords: crumb rubber, bitumen, modification, polymer, improvement, quality, recycling, analysis, research
