The purpose of the study is to obtain a durable and cheap road-building material based on ash, reinforced with mineral astringent. Within the framework of the research, the optimal dosages of binders were searched for, the characteristics of the strength of mixture of ash with sludge and ash with cement were also determined. A comparative analysis of the economic efficiency between using a mixture of ash from the incineration of sewage sludge, reinforced with nepheline sludge, and traditional road building materials was carried out. The results of the study of mixtures of ash with mineral binders, such as nepheline sludge and cement, show that the obtained materials have high strength indicators and high indicators of the modulus of elasticity. They can be attributed to strength grades from M20 to M100. The developed building material (ash mixed with binders (nepheline sludge, cement)) could replace a similar building material in the technology of road construction, because if this mixture is taken in optimal dosages, it will be more profitable in the process of use, both from the point of physical and mechanical views, and point of view of economic indicators.
