The paper describes the production of modifying additive on the basis of waste - deferrization sludge of waste groundwater of Nekrasovskoye settlement, Yaroslavl region. The authors found that the predominant components of this waste are trivalent and divalent colloidal iron in the ratio of 3:1. The authors propose to use this waste as a modifier of asphalt concrete mixture to increase the adhesion of bitumen to mineral components based on the study of its physical and chemical properties. The authors have conducted studies of mixes of various grades and selected optimal conditions for the use of deferrization sludge in the technological process of asphalt concrete production. The use of modifying additive allows to increase shear stability and water holding capacity of asphalt concrete.
