The article presents the results of a study of the main characteristics of ash selected from the ash dumps of CHP-3 in Almaty. It is shown that the operation of thermal power plants in Kazakhstan is characterized by a significant amount of accumulated (more than 500 million tons) ash and slag waste. It has been established that the storage and storage of ash and slag causes a very significant impact on the environment in the area of their location. Therefore, it is very important to address the issues of reducing the burden on the environment by developing technologies for the disposal of ash and slag and their use in road construction. The results of a study of the physical and technical characteristics of a binder based on bitumen and ash slag are presented. The study of samples using bitumen and slag binder showed that they meet the requirements of regulatory documents. The research results can be useful in solving the environmental problem of ash and slag waste disposal, which will reduce the volume of ash dumps, as well as free up occupied land for economic needs.
