Automobile roads perform a particularly important, responsible function in the movement of every automobile, transport equipment. The quality of automobile roads determines the reliability of road construction and automotive equipment, the resource of their work, and, most importantly, ensuring traffic safety. However, the construction of roads and construction methods with the expiration of a certain time undergo significant changes associated with the intensive development of road transport, road construction equipment, an increase in the intensity and flow of traffic. In this regard, there is a need to build high-quality roads and cover roads with durable concrete, which can be achieved by upgrading with composite chemical additives in the composition of concrete - a modernized superplasticizer. The object of this work is a superplasticizer for producing wear-resistant concrete. The introduction of a superplasticizer into the composition of concrete makes it possible to obtain especially strong concrete with an increased service life, which in turn will significantly reduce material costs for raw materials, repair work, and labor resources. The purpose of this study is to obtain a highly effective superplasticizer and particularly durable wear-resistant concrete for road surfaces. To achieve this goal, it is necessary to solve the following tasks: prepare raw materials, develop an optimal component composition and obtain a superplasticizer; in laboratory conditions to obtain a prototype of concrete; determine the quality indicators of the resulting concrete by GOST; to conduct pilot tests for implementation in production.

The technological properties of cement stone modified with a plasticizing complex chemical additive KDj-3CHMB have been studied. The influence of the additive on the basic properties of the cement stone has been investigated. The results of the research are given, indicating the active participation of improving the performance of concrete, as well as the possibility of reducing the amount of cement to 10-15%. The content of the additive KDj-3CHMB in the composition of the cement stone leads to an increase in its density by 7-10% and prismatic strength by 40% in comparison with the control samples. At the same time, the complex chemical additive KDj-3CHMB increases the indicators of mobility and frost resistance of cement stone
