“…Induction heating is a complex phenomenon that combines the electromagnetic and heat transfer theory and has a strong relationship with the electro-thermal properties of materials [22][23][24]. Furthermore, it is known that the efficiency of the induction heating depends on the coupling between the size of the inductive particles and the operational characteristics of the induction coil (frequency, power, shape of the induction coil, etc.).…”

h i g h l i g h t sApplication of advanced tools enables the implementation of induction technology for healing in asphalt mixes. Induction heating and healing potential of asphalt mortar using different inductive particles types is studied. An optimization framework for the design of induction healed asphalt mortars is proposed. The increase of inductive particles contributes to the electro-thermo-mechanical performance improvement and the healing potential of asphalt mixes. a b s t r a c tInduction heating technique is an innovative asphalt pavement maintenance method that is applied to inductive asphalt concrete mixes in order to prevent the formation of macro-cracks by increasing locally the temperature of asphalt. The development of asphalt mixes with improved electrical and thermal properties is crucial in terms of producing induction healed mixes. This paper studies the induction healing capacity of asphalt mixes without aggregates as the part of asphalt concrete where inductive particles are dispersed notably contributing to the final response of asphalt pavements. Special attention was given to the characterization of inductive asphalt mixes using experimental techniques and numerical methods. The research reported in this paper is divided into two parts. In the first part, the impact of iron powder as filler-sized inductive particle on the rheological performance of asphalt-filler systems was studied. The mechanical response, the induction heating and healing capacity of asphalt mortar by adding iron powder and steel fibers was evaluated as well. In the second part, the utilization of advanced finiteelement analyses for the assessment of the induction heating potential of inductive asphalt mortar with steel fibers are presented. The influential factors of induction mechanism in asphalt mixes are also described. The experimental and numerical findings of this research provided an optimization method for the design of induction healed asphalt concrete mixes and the development of necessary equipment that will enable the implementation of induction technology for healing of asphalt concrete mixes.

“…The devices employing ferromagnetic core have been used in clinical experiments [6][7][8] but it is difficult for them to further improve the frequency and intensity of the AMF due to the large volume of the core and significant self-heating inside it. With smaller volume and less self-heating, the induction coil, which generally based on resonant inverters, was used and researched more and more frequently [5,[9][10][11].…”

Abstract. BACKGROUND: Induction heating devices using the induction coil and magnetic nanoparticles (MNPs) are the way that the magnetic hyperthermia is heading. OBJECTIVE: To facilitate the induction heating of in vivo magnetic nanoparticles in hyperthermia experiments on large animals. METHODS: An induction heating device using a planar coil was designed with a magnetic field frequency of 328 kHz. The coil's magnetic field distribution and the device's induction heating performance on different concentrations of magnetic nanoparticles were measured. RESULTS: The alternating magnetic field produced in the axis position 165 mm away from the coil center is 40 Gs in amplitude; magnetic nanoparticles with a concentration higher than 80 mg. mL −1 can be heated up rapidly. CONCLUSION: Our results demonstrate that the device can be applied not only to in vitro and in small animal experiments of magnetic hyperthermia using MNPs, but also in large animal experiments.

“…The non-uniformity of the lateral distribution of electric current in the cross-section of the conductor due to approximate effects can be effectively eliminated using various heating distances. Also, the uniformity of the temperature of the heated surface can be thus improved [11].…”
