FIELD: metallurgy. SUBSTANCE: in a method of processing melted slag to produce binding agent for paving blends, as correcting additive, calcium-containing substances are used decomposing at slag melting temperature to form free calcium oxide which must be present in slag mass at weight ratio from 1.82: 1 to 2.1:1 with regard to silicon oxide to produce bicalcium silicate on slow unaffected cooling, after which slag mass obtained is slightly ground and submitted to dry magnetic separation. Resultant binder for paving blend exhibits uniform growth of strength in the course of time. EFFECT: improved performance characteristics of pavement. 1 tbl
