Shulgin State Road Research Institute State Enterprise popup.description2 The object of research is bitumen modified with surfactant-based additives. The subject of research is to clarify the requirements for the production and use of bitumen modified with surfactants. Research methods - analysis of literary sources, laboratory research. A review of the literature on methods for evaluating the effectiveness of surfactant-based additives by determining changes in the interaction of bitumen with aggregate and depending on the maximum size of the aggregate and bitumen viscosity. The influence of the conditions of preparation of the studied materials, the procedure of thermal stabilization and technological aging on the adhesion of bitumen to aggregate with a grading of more than 10 mm, with a grading of 0.125 mm to 10 mm and with a grading of less than 0.125 mm was determined. Proposals have been developed to improve the specification of requirements for the production and use of bitumen modified with surfactant-based additives.
