JUSTIFICATION OF THE FEASIBILITY OF USING FLY ASH IN ROAD CONSTRUCTION

Vyacheslav Savenko Viktor Skoropadskyi

This paper describes in detail the characteristics of waste from the coal industry and thermal power plants, namely ash removal. The nature of formation, chemical composition, physical characteristics and ash classification are indicated. The problems of world utilization of technogenic waste of thermal power plants are considered. The main directions of use of the material with obtaining the most positive consequences are indicated. The feasibility of using ash in different fields and the peculiarities of use have been studied. All areas of use are substantiated by the positive qualities that are generated by the application of ash. The expediency of using ash ash is substantiated, which has a positive effect on the saving of materials and the environmental situation. The influence of ash on each of the methods in which it is used is indicated. Problems that arise in parallel with the application of this material are analyzed. The mechanisms of interaction of fly ash with other materials and the consequences that follow from this are indicated. Affected environmental situation and ways to improve it through the use of ash. Based on research and observations, a conclusion is drawn
