摘要：
The key point of preparing conductive asphalt concrete for deicing and snow melting is pavement performance must satisfy the requirements before it can melt snow successfully. This study prefers to prepare electrically conductive asphalt concrete choosing steel slag as the whole aggregates and conductive minerals, while mixed with graphite and carbon fiber. Moisture susceptibility has been evaluated through water-saturated Marshall Stability test and indirect tensile splitting strength test. High temperature performance and fatigue performance were analyzed through dynamic creep test and indirect tensile fatigue test. Results indicate: High temperature performance of steel slag conductive asphalt concrete is better than ordinary basalt asphalt concrete, while its moisture susceptibility and fatigue performance is not good enough and need to be improved.
