APPLICATION OF ‘NORILSK NICKEL’ MINING-METALLURGICAL COMBINE INDUSTRIAL WASTE IN ROAD ASPHALT CONCRETE PRODUCTION
The paper deals with the issues of using Krasnoyarsk territory industrial waste for road asphalt concrete production. It presents the results of studying neutralization final tailings and granulated slag of copper-nickel production of Norilsk Nadezhdinsky plant. It is shown that the final tailings of neutralization can be used as mineral powder while granulated slag can be used as fine aggregate in the composition of the road asphalt concrete. The industrial waste-based compositions of the road asphalt concrete have been developed and tested both in laboratory and in-situ experimental conditions. Economic efficiency of industrial waste application in asphalt concrete is calculated.
