Abstract: Icing on the roads causes traffic accidents and delays. Anti-icing is divided into two as passive (traditional) and active (modern) methods. Traditional methods may not always be successful in preventing icing due to lack of icing consumables, equipment and personnel, environmental concerns, etc. This has necessitated the development of more effective, environmentally friendly, sustainable methods such as electrically conductive asphalt concretes (CAC). In this study, there are two different conductive asphalt concrete (CAC) groups, Series 1 and Series 2. Both groups contain carbon fiber as a conductive component and their aggregates consist of basalt in the coarse fraction, and limestone-based aggregates in the fine aggregate and mineral fillers. Series 1 samples were produced from bitumen without additives as binder, and Series 2 samples were produced from bitumen modified with 14% carbon black used to increase electrical conductivity. To investigate the electrical conductivity properties of CAC samples, resistivity measurement, thermal distribution measurement, ice melting performance and repeated freezing-thawing with electrical conductivity tests were performed. Then, to investigate the mechanical properties of CAC samples, Marshall stability-flow, indirect tension and Cantabro tests were performed. In addition, a comparative cost analysis was performed for CAC and conventional asphalt concrete. As a result of the study, it was understood that the produced CAC samples can be used in preventing icing, however, CAC electrical conductivity properties are also affected by the type of mineral aggregate.

Learning Objectives:

Attendees can expect to learn the following from this session:
  • Explain the effects of electrically conductive asphalt pavements modified with carbon black on electrical conductivity.
  • Explain the effects of basalt aggregates on electrical conductivity in electrically conductive asphalt pavements.
  • Compare the ice melting performance of electrically conductive asphalt pavements.
