Abstract. This article discusses the problems that arise in the operation of road structures. One of the most important is rutting. Indicators of resistance to rutting depend on the method of design of non-rigid pavement and operational parameters, which allows to obtain the applied method of volumetric design of asphalt mix «Superpave» (SP-19), which in our country was called «SPAS». The authors, together with the staff of the laboratory of asphalt Concrete plant – 1, monitored asphalt concrete mixtures designed according to the «Superpave» system on the asphalt mixing plant. Then tests were carried out according to the method of PNST 181-2016 on the susceptibility of asphalt concrete materials to shear deformations arising under the action of repeated passes of the loaded wheel at ambient temperature. The result of the study of rutting showed that the mixture SP-19 have predominantly traditional. More detailed research results are presented in this article. Based on the data obtained from the results, conclusions were formulated: the Studies show that the method of «Superpeyv» is updated to the requirements of technical supervision at the objects of the road complex of the Russian Federation. In conclusion, the authors have formulated conclusions on the research: a comparison of physical and mechanical performance of asphalt concrete mix SP-19 on PNST 114 and fine-grained asphalt concrete mix type A brand I shows that the shear stability in terms of the average depth of the track is higher for the brand SP-19 by 38 %; set the required mixing temperature and compaction of asphalt concrete mixture on the system «Superpeyv»; the release of a pilot batch of asphalt concrete mix of SP-19 brand at the production site of JSC «ABZ-1» showed that the recipe selected in the laboratory is reproduced in the ABZ; cores selected within the framework of technical supervision from the experimental coating and tested in the laboratory showed corresponding to the requirements of ODM 218.4.038-2017; assessment of economic efficiency at the cost of asphalt concrete mix of SP-19 brand showed a decrease of 2.2 % relative to the cost of fine-grained asphalt concrete mix; the increase in the service life of the road surface h 30–50 % by reducing rutting increases its turnaround time. At the same time, economic efficiency can reach 50 % per m².
