This study evaluated the technical potential of a stabilizer derived from the intimate mixture of steel waste (powder electric arc furnace oxidizing slag - PES) and fly ash to improve soil engineering properties for application in urban paving. This evaluation was performed by laboratory tests to characterize, through CBR tests and unconfined compression tests, the mechanical behavior of compacted residual soil samples of the Alto Paraopeba region, state of Minas Gerais, Brazil, and mixtures of these soils with the stabilizer. For the peculiarities of the research, it was possible to demonstrate the technical viability of the use of steel waste in urban paving works, highlighting the relevance of the proposal in meeting the needs of steel companies to confer a sustainable disposal of waste materials, and the need of municipalities surrounding such companies to providing for, with low-cost materials, significant demands of unpaved road networks.
