    Conductive asphalt concrete can eliminate snow and icing on road areas, and is a research hot topic for intelligent snow removal. By adding graphite, the electrical resistivity of asphalt concrete can be reduced to achieve the purpose of electrical conductivity. However, the aggregate electrical resistance in asphalt concrete is very large and does not play a conductive role. It is a new technical idea to use steel slag with good electrical conductivity as aggregate to mix graphite powder with good electrical conductivity to prepare steel slag graphite conductive asphalt concrete (SGCAC). In this paper, the effects of steel slag and graphite on the conductive properties of steel slag graphite conductive asphalt concrete are separately explained, and then the conductive mechanism and electrical resistance stability of the conductive slag and graphite are studied.

    Research progress of steel slag asphalt concrete
    (Édition Diffusion Presse Sciences, 2020) Akmaldinova, Oleksandra; Krayushkina, Kateryna; Bieliatynskyi, Andrii; Sun, Jian; Акмалдінова, Олександра Миколаївна; Краюшкіна, Катерина Вікторівна; Бєлятинський, Aндрій Олександрович; Сан, Юан
    Steel slag asphalt concrete is one of the important components of asphalt concrete. There are some differences between the steel slag asphalt concrete and ordinary asphalt concrete. Based on the research of scholars at home and abroad, this paper systematically introduces the steel slag characteristics and excellent performance of steel slag asphalt concrete, summarizes the problems existing in the practical application of steel slag asphalt concrete, and provides references for its promotion and application.
