description: This work is devoted to the study of the granulometric composition of asphalt concrete mixture, the prediction of possible defects of the pavement, based on the structure of this composition, as well as the development of a methodology for assessing the quality of the granulometric composition of asphalt concrete mixture for its use in production conditions with the prospect of improving the quality of manufactured asphalt concrete mixtures. In the course of this study, the following tasks were solved: 1. the regulatory framework and scientific literature in the field of designing asphalt concrete mixtures have been studied and analyzed; 2. several asphalt concrete mixtures prepared with various granulometric compositions have been selected; 3. the granulometric compositions of the asphalt concrete mixtures under consideration are determined; 4. graphs of the data of granulometric compositions are constructed with a line of the maximum density of the asphalt concrete mixture displayed on them; 5. the structures of the studied samples of asphalt concrete mixtures were decomposed into substructures using the Bailey granulometric composition estimation technique; 6. additive convolution of experimental results was carried out and a methodology for assessing the quality of asphalt concrete mixture was formulated; 7. the relevance of the formulated methodology is substantiated and practical recommendations for its application in production conditions are prepared. In the course of this study, several granulometric compositions intended for the preparation of asphalt concrete mixtures were screened on the basis of the accredited testing road construction laboratory of LLC âRoad Production Associationâ. Based on the result of the screening, graphs of these granulometric compositions were compiled, and Bailey criteria for each sample of the mixtures were calculated. Then, using additive convolution, the obtained qualitative indicators were reduced to a single criterion reflecting the quality of the mixture for each sample under study. As a result of the work carried out, a methodology for assessing the quality of the granulometric composition of asphalt concrete mixtures was formulated on the basis of a number of experiments conducted. An economic justification has been prepared for this technique, reflecting the effectiveness of its application, as well as practical recommendations for its use in production conditions.
