Coal ash and slag are to become key components of highway paving

Coal ash and slag are to become key components of highway paving, Kubrakov says. As demonstrated in the US and EU, use of these industrial wastes can cut highway construction costs by 30%. Ukraine generates 7.5 million tons of ash and slag waste every year. Use is to be concentrated in four southeast regions with large concentrations of thermal power plants: Donetsk, Dnipropetrovsk, Kirovohrad, and Zaporizhia. “In all these regions we definitely want to use ash and slag,” says the head of the highway agency.
