Abstract

It is important for conductive asphalt concrete for deicing and snow-melting to have a good electrical resistance stability.Electrical resistance stability of the conductive asphalt concrete using steel slag as aggregate (CACS) is investigated.Effects of temperature,chloride solution,and load-unload cycles on the electrical resistivity of CACS are studied.Resultsshow that the electrical resistivity of CACS slightly changes with time and exhibits good stability in the chloride solution.CACS exhibits obvious positive temperature coefficient,that is,the electrical resistivity of CACS increases as temperature increases.The electrical resistivity of CACS decreases as compressive stress increases,and somewhat increases but cannot recover to the original electrical resistivity value after unloading.
