Abstract:
During periods of snow, freezing rain, icing on road surface could cause to transportation safety problems and interrupt the traffic especially some critical sections of roads such as tunnel, bridges and vertical and horizontal curves of roads and etc. Recent years one of the technologies used to help pavement snow melting/de-icing by an asphalt pavement electrical heater is electrically conductive asphalt concrete. Electrically conductivity is ensured by the conductive material added into asphalt concrete. It was known from literature that various conductive materials can be used in asphalt concrete. In this study asphalt concrete specimens with 5, 10 and 15 mm length and 0.1, 0.2, 0.3, 0.4 and 0.5% by weight carbon fibre (CF) additive were produced. Conductivity properties relation with CF characteristics was determined and test results were assessed.
