Investigation the Carbon Fiber Based Conductive Asphalt Mixtures for Anti-icing
In recent years, researchers have been working on a new type of t pavement called electrically conductive asphalt to be anti-icing. In this study, hot mix asphalt (HMA) stone mastic asphalt (SMA) specimens were prepared by adding carbon fiber (CF) in three different lengths (5-10-15 mm) and five different ratios (0.1-0.2-0.3-0.4 and 0.5 by weight). As a result of the study, it was determined that the CF properties and aggregate gradation difference were quite effective on the electrical conductivity, and the electrical conductivity properties also changed depending on the CF length and percentage in the mixtures. According to the electrical conductivity test results, it was observed that the 5 mm length of carbon fiber specimens is more suitable for use in electrically conductive asphalt mixtures (CAM).
