description: The purpose of this work is to determine the degree of influence of modifiers on the indicators of crushed-mastic asphalt concrete, including those necessary for the calculation and design of non-rigid road pavements. The tasks that were solved in the course of the study: 1. Analyze methods and materials for modifying asphalt mixtures and the extent of their influence on the design characteristics. 2. To prepare an experimental plan, crushed-mastic asphalt mixtures with modifiers and samples to study the effect of complex modifiers on the selected indicators of asphalt concrete SMA-16 3. Identify the most optimal content of modifiers and conduct comparisons between the results of mixtures with different additives. 4. To give recommendations on the use of modified asphalt concrete. The work was performed with the use of materials and test facilities of the laboratory of the SPB GKU "Directorate of Transport Construction" of the Department of Quality Control and Implementation of Innovations. In the course of the study, mixtures were prepared using three modifiers for the SMA-16 with three levels of modifier content. Samples were made of the prepared mixtures to determine such indicators as: binder flowability, air void content, Marshall breaking load, Marshall deformation, average rut depth, rutting curve slope angle, ultimate bending tensile strength, ultimate relative stretching strain and asphalt concrete abrasion resistance. Regression curves of dependence of indicators on the content of modifiers were calculated according to the obtained results, a multi-criteria evaluation was carried out to determine the most optimal modifier for application and practical recommendations were given for the application of the obtained results of the study.
