Unravelling porous asphalt concrete with Induction Heating
Construction and Building Materials, 2014Co-Authors: Quan Tao Liu, Erik Schlangen, Gerbert Van BochoveAbstract:Abstract Ravelling is the main defect of porous asphalt pavement. An unravelling porous asphalt was developed in this research. Steel wool was added to porous asphalt concrete and Induction Heating was used to heal the cracks at early stage to prevent ravelling. In this paper, the mixing procedure was optimized to disperse steel wool into asphalt mixture, the Induction Heating potential of porous asphalt concrete containing steel wool was measured, and Rotating Surface Abrasion Test with rest periods to apply Induction Heating was employed to study the ravelling resistance improvement of porous asphalt concrete. It was found that porous asphalt concrete containing steel wool can be heated with Induction energy and Induction Heating can greatly reduce the stone loss of porous asphalt concrete, despite when Induction Heating was applied. Porous asphalt suffered less ravelling damage when Induction Heating was applied at an earlier stage. It is concluded that unravelling porous asphalt can be achieved by applying Induction Heating and Induction should be applied at an early stage.

Induction Heating of asphalt mastic for crack control
Construction and Building Materials, 2013Co-Authors: Qian Liu, Quan Tao Liu, Shaopeng Wu, Erik SchlangenAbstract:Asphalt mastic is a self-healing material and it has the potential to close internal cracks by itself. In this study, an Induction healing approach is developed to increase the self-healing capacity of asphalt mastic. Conductive additives are added to asphalt mastic to make it electrically conductive and suitable for Induction Heating. When micro-cracks are expected to occur in asphalt mastic, Induction Heating can be to improve the self-healing ability of asphalt mastic to close the cracks. This paper investigates the Induction Heating speed, bending strength and Induction healing rate of asphalt mastic with different conductive additives. It was observed that asphalt mastic that contained steel wool or steel fiber can be rapidly heated using Induction energy. Adding steel wool or steel fiber to asphalt mastic also increases its bending strength. Finally, the fractured asphalt mastic beams that contain steel wool and steel fiber can regain their bending strength to that of fresh reference samples with Induction Heating. Cracks were observed to disappear during Induction Heating. Based on these results, it is concluded that Induction Heating/healing can be used to close cracks in asphalt mastic.

Induction Heating of electrically conductive porous asphalt concrete
Construction and Building Materials, 2010Co-Authors: Erik Schlangen, Alvaro GarciaAbstract:Abstract In this research, an electrically conductive porous asphalt concrete, used for Induction Heating, was prepared by adding electrically conductive filler (steel fibers and steel wool) to the mixture. The main purpose of this paper is to examine the electrical conductivity and the indirect tensile strength of this conductive porous asphalt concrete and prove that it can be heated via Induction Heating. It was found that, to make porous asphalt concrete electrically conductive, long steel wool with small diameter is better than short steel fibers with bigger diameter. However, steel fibers with short length and big diameter have better strength reinforcement capability than steel wool with long length and small diameter. It was also proved that conductive porous asphalt concrete containing steel wool can be easily heated via Induction Heating. Finally, 10% (by volume of bitumen) of steel wool type 000 was proposed as an optimal content in porous asphalt concrete to obtain an optimal conductivity, a good Induction Heating rate and an acceptable indirect tensile strength. It is expected that the autogenous healing capacity of asphalt concrete will be enhanced with the increase of temperature during Induction Heating.

Thermal and magnetic field analysis of Induction Heating problems
Journal of Materials Processing Tech, 2005Co-Authors: Hiroki Kawaguchi, Masato Enokizono, Takashi TodakaAbstract:This paper presents results of finite element analysis of Induction Heating problems considering temperature dependence of material characteristics. In this analysis, we have used the three-dimensional finite element method in order to correctly express Induction Heating coil's shapes and to make clear its effects on temperature distributions. The heat-conducting problem and the eddy current problem are coupled, and solved by using the step-by-step calculations.
