Abstract:

In order to explore the conductive heating characteristics of conductive asphalt and mixture near the crack, conductive asphalt and mixture with different proportions were prepared and the conductive healing test was conducted. An infrared camera was used to measure the temperature field around the crack. Digital image processing technology was used to quantitatively analyze the healing level of conductive asphalt. The repeated healing properties of asphalt mixture were analyzed. Results show that the temperature of conductive asphalt and mixture both linearly increase with the charging time. There is an exponential function relationship between the heating rate and electrical resistivity. The temperature of the area near the crack of conductive asphalt and mixture is notably higher than that of others, and the local temperature rise obviously. The local high temperature is conducive to realize the target healing of cracks. The repeated healing index of asphalt mixture gradually decreases with the increasing of fracture cycles. The healing temperature and electrifying time have significant effects on the healing index. The ratio of resistivity before and after healing can be used to estimate the healing level of conductive asphalt mixture.
