In connection with the sharp increase in the traffic flow, the problem of the durability of asphalt concrete pavements comes to the fore – their ability to maintain their properties within a certain period of time within certain limits. In many respects, the quality of future coverage is laid by the adaptability of the laying process, strict compliance with the requirements of project documentation and existing building codes and regulations (SNiP, GOST, ISO, etc.). However, the technology itself of the process of making asphalt concrete pavements is constantly evolving – new complexes are emerging, changes are being introduced to existing structures of machines for building coatings. Addition, reduction and combination of operations of the technological process, including, against the background of improving the quality and, as a result, the durability of the coating, reduce the complexity of the work performed, reduce the number of necessary staff – all of this has a positive effect on the economic component of construction, frees up additional funds. And, as you know, there is already enough evidence that the main factor hindering the development of the road network in the Russian Federation is, just the same, the need to spend huge budget funds (in 2016, about 30 billion rubles were allocated from the federal budget to repair existing roads due to their poor condition). In turn, the road-building industry, which is developing at a high pace, sets stringent requirements to ensure the required level of quality throughout the entire process, starting from the places of production of asphalt-concrete mixture (ABZ).
