It is shown that about 60% of metallurgical waste is a source of pollution of the urban ecosystem. The obvious solution to the “problem of solid waste” of metallurgical production is their construction and technological disposal. The problem of involving steelmaking slag in economic activity continues to be relevant for large metallurgical industries, whose annual production volumes of this by-product amount to millions of tons. Road construction is one of the priority sectors. It is established that in the process of further processing of slags (crushing and fractionation), it is recommended to provide additional measures for the separation of pulverized fractions to the value normalized by the current documents for the preparation of crushed stone-sand mixtures of type C5–C8. The implementation of the developed compositions for the construction of the bases of road pavements at the facilities of the Lipetsk region has been carried out. When splinting with slags of optimal granulometry, the modulus of elasticity of the road base increases slightly (by 5.1% compared to a conventional base without splinting). It has been proved that the organization of separate collection of the main components of mixed steelmaking slag will make it possible to produce ready-made active crushed stone-sand or sand mixtures, the introduction of more efficient design solutions for pavement structures, characterized by high transport and operational performance, with the use of steelmaking slags.
