The article states that the service life of road surfaces for federal highways is determined by the Russian Government Resolution No. 658 of May 30, 2017 and is 24 years for all categories. In the previous Resolution (dated August 23, 2007, No. 539, as amended in 2015), these terms were 12 years. It is noted that the doubling of inter-repair periods should be accompanied by a sharp increase in the quality of road construction, the emergence of breakthrough design, structural and technological solutions, but major repairs of road pavements are still carried out after 10-12 years, usually referring to harsh climatic conditions, increased traffic loads, design flaws, violation of technology. Even with high-quality paving, there are areas in asphalt concrete pavements that show signs of destruction after the first season of operation. These are joints in the body of the pavement, where the newly laid mix adjoins the previously laid mix. It is emphasized that the reason is trivial: at the points of contact it is very difficult to ensure the required density and monolithicity of the mixture. It was proposed to solve the problem of “splicing” of adjoining fragments of the pavement layer on the basis of application of bituminous-polymer jointing tapes, as in Russia there is already experience of their application, and monitoring of the pavement condition in the joint zone shows that the use of bituminous-polymer jointing tapes provides significant advantages by ensuring monolithic jointing during the period of the pavement pavement paving.
