Abstract: In this work, the adhesiveness of petroleum road oxidized bitumen grade BND 50/70 according to DSTU 4044, manufactured by the LOTOS Asfalt company (Gdansk, Poland) and petroleum road oxidized bitumen grade BND 70/100 according to DSTU 4044, originating in Kazakhstan, was investigated. material - dense granite crushed stone, fr. 20-40 mm selected from "Mokryansky Stone Quarry No. 3" LLC, without and with the use of adhesive additives of domestic and foreign production according to two research methods: adhesion to crushed stone, adhesion to the surface of glass. The purpose of the research: To modify bitumens with selected adhesive additives and establish the adhesion of bituminous binders to the surface of stone materials and glass. Objectives of the study 1. Conduct a critical review of sources regarding the adhesion of road bitumen with adhesive additives 2. Select materials for research, namely raw bitumen, stone material, adhesive impurities. 3. Use in research and characterize the following methods: adhesion to crushed stone, adhesion to the surface of glass. 4. Investigate adhesion of original and modified bitumen with adhesive additives of domestic and foreign production according to selected research methods Subject of research: bitumen modified with adhesive additives of domestic and foreign production. The object of the study: adhesion of modified bitumen according to the methods of adhesion with crushed stone, adhesion with the surface of glass. Key words: adhesive admixtures, modified bitumen, adhesion to crushed stone, adhesion to the surface of glass. References 1. DSTU 8787:2018 Bitumen and bituminous binders.
