In addition, carbon fibers are electrically conductive. As an additive to asphalt, they can reduce the electrical resistivity, which may have applications in asphalt stress testing, structural vibration sensing, and heating roads to melt ice and snow. Precautions are needed during the addition of carbon fiber to hot mix asphalt.
