“…During electromagnetic induction, the elements that can be heated are Fe, Co, and Ni [12]. e optimal content of fiber is 6% by the volume of asphalt according to the previous research [4]. Asphalt mixture with 6% steel wool fiber has best mechanical properties (highest strength and particle loss resistance) and quite high induction heating speed.…”

“…e thermal constants were measured in 4 regions of the center, and the mean value was taken for 3 times for each part, that is, 12 times for each kind of asphalt concrete. Figure 6, was divided into two parts: induction temperature and induction healing, where the distance from the surface of the sample to the coil was kept constantly at 10 mm [4]. e induction temperatures of both tests were monitored by an infrared camera with a resolution of 320 × 240 pixels.…”

“…Asphalt concrete pavement has attracted more and more attention because of its excellent service performance [1][2][3][4][5]. However, due to environmental and human factors, such as temperature [6], moisture [7], ultraviolet rays [8], and heavy load [9], it is often difficult for the service life of the asphalt concrete pavement to reach the design life.…”

It is consensual that the self-healing property of asphalt concrete can repair the damage inside it during high temperature and rest period. In order to not affect the traffic, the rest period of asphalt pavement is very short and uncontrollable; so, it is necessary to obtain enough high temperature in a limited time to achieve higher healing efficiency of asphalt concrete. The purpose of this paper is to study the induction heating efficiency and healing behaviors of asphalt concretes doped with different conductive additives. Steel fiber, steel grit, and steel slag were added to asphalt mixtures as conductive additives to prepare induction healing asphalt concretes. The steel grit and steel slag were added to replace the aggregates of corresponding particle size by equal volume to ensure the consistency of asphalt concrete volume, which can avoid degrading the performance of asphalt concrete due to the change of porosity. The induction heating efficiency and healing rate of asphalt concrete were quantified by infrared camera and three-point bending-healing experiment, respectively. The results showed that the thermal properties of asphalt concrete changed with the addition of different conductive additives. The asphalt concrete with steel fiber had the best induction heating property. While steel slag had extremely weak induction heating speed, the better thermal insulation property of the asphalt concrete with steel slag resulted in a higher induction healing rate. It was suggested to add steel slag to induction healing asphalt concrete to improve the healing rate.

“…They found that the PSV value of EAFS aggregates was way much higher than conventional aggregates such as quartzite gravel and diorite. Liu et al (2018) evaluated the heating characteristics and induced healing efficiencies of asphalt mixtures via induction and microwave heating. In this context, asphalt samples were heated by two heating methods:…”
