AB Electric Arc Furnace (EAF) slag, a waste stream in the production of carbon steel, has interesting and extensively researched mechanical properties as an aggregate in asphalt mixes. In this paper, an exhaustive review is conducted of its main features, the problematic aspects of its use, and the main properties of the mixes prepared with this aggregate, such as mechanical behaviour, resistance to fatigue and permanent deformation, water sensitivity and skid resistance. Based on the literature review and own experience, the conclusion is that the use of EAF slag is generally recommended in partial replacement of the coarse aggregate, in all types of asphalt mixtures, following suitable pre-treatment. This usage improves mechanical performance, durability and long-term sustainability of the bituminous mixtures. Moreover, resistance against slipping and skidding on EAF slag pavements is an important safety-related aspect that makes them especially suitable for rainy regions.
