Abstract

This scientific text examines the analysis of domestic and world experience of using ash slag materials of thermal power plants in road materials produced by cold recycling technology. Coal is the most important primary source of energy in Ukraine. In 2019, its share accounted for 28.9% of all energy resources. There are 15 coal-fired power plants in Ukraine, the total capacity of which is 30-40% of the total installed power generation capacity in the country. As a result of the operation of thermal power plants (TPP), a significant amount of large-tonnage waste - ash and slag materials (ZShM) is generated. 360 million tons of ash slag are accumulated in TPP ash dumps. About 5-10 million tons of ash and slag are produced annually. Therefore, there is a question of reducing waste materials as materials for road construction. In Ukraine, the main method of using fly ash materials is their use in the production of cement. But at the current level of cement production, the potential of using slag in this industry has been exhausted. Therefore, the question of using ash slag materials in other industries arises. As an option, it is the use of ZSHM in road construction
