Research on the preparation of conductive asphalt concrete for deicing and snow melting

摘要

Conductive asphalt concrete has the characteristic of giving off heat after energized, so that the ice and snow could be melted in a short time. Subsidized by National Science & Technology Pillar Program of China (2008BAG10B01), in this paper, carbon fiber and graphite is selected to be conductive material, target proportioning of AC-20 gradation is designed, the optimum asphalt aggregate ratio is worked out, the mixing pattern of asphalt mixture is chosen, and the relationship between the dosage of the conductive material and the electrical performance of the conductive asphalt concrete is researched.
