However, it is often affected by transverse cracks of temperature-shrinkage origin. Cracks are the source of further destruction and lead to premature failure of both the coating itself and the structural members. With the formation of cracks, the surface of the coating gradually deteriorates, the safety and comfort of movement decreases, transportation and repair costs increase. Crack repair is a complex, time-consuming and expensive process, accompanied by considerable material and energy costs. At the same time, the performed repair measures do not always allow to achieve the desired result in the durability of the repaired structure. Analysis of existing provisions of GBNV.2.3-37641918-557: 2016 “Highways. Roadwear is tough. Designing ”on the design and calculation of asphalt concrete pavement of hard road clothes, other normative and technical documents and technical literature in the field of research. Experimental studies (field or bench tests of at least 4 types of coating) have been carried out to ensure the fracture toughness and shear resistance of asphalt concrete coating on cement concrete basis. Clear requirements for the state of the cement-concrete base were established, the principles of construction and rules for the calculation of hard pavement with asphalt-concrete pavement to ensure its crack and shear strength were specified and expanded. An appropriate guide to GBN B.2.3-37641918-557: 2016 has been developed and set out and issued in accordance with SOA 42.1-37641918-008: 2016.
