The best electro-thermal performance was achieved with 6% recycled metal fiber and carbon black modified binder, enhancing ice melting.
Energy consumption for heating the pavement cores was measured at 1623 W/m², significantly lower than previous studies.
Full-scale pavement testing was conducted in northwest Iran, utilizing a comprehensive laboratory analysis on field samples.
These findings suggest that electrically conductive asphalt can effectively protect pavements from extreme winter conditions.
