description: This work is devoted to the development of experimental and computational methods for designing the composition of an asphalt concrete mixture based on full-scale and computational experiments to create an optimal structure of asphalt concrete with predetermined properties that should provide the required operational characteristics of the road surface being constructed. In the course of the study, the analysis of the types of asphalt concrete materials and coatings from them was carried out, the methods of designing asphalt concrete were investigated, and promising ways to improve the physical and mechanical characteristics of asphalt concrete were identified. The next step was to determine the physical and mechanical characteristics of asphalt concrete using the methods of correlation analysis, the design procedure using the theory of experiment planning was presented, and regression equations were obtained. In conclusion, the substantiation of a methods for increasing the physical and mechanical characteristics of asphalt concrete is presented, practical recommendations for the use of experimental and computational methods for designing asphalt concrete are formulated, and a comparative analysis of design methods for reliability and efficiency is made. Experimental studies were carried out on the basis of the road-building quality control laboratory of the St. Petersburg State Institution "Directorate of Transport Construction". A mathematical model for assessing the physical and mechanical characteristics of asphalt concrete mixtures has been built. Experimental and computational methods of designing asphalt concrete mixtures are presented. The principles of their application are stated.
