Mechanical and sustainability assessment of induction heatable asphalt tiles and asphalt pellets in road maintenance

Abstract: In this paper, two new methods for pothole repairing are proposed, assessed and compared. The first method is a combination of a prefabricated asphalt tile and a bonding layer that can be placed into a sanitized pothole and bonded by applying electromagnetic induction heating. The second approach consists of the prefabrication of asphalt pellets that can directly fill a given pothole and be heated by induction. By combining prefabrication and on-site induction heating, both methods offer high-quality mechanical performance while reducing the production of debris and noxious fumes. They can also improve work conditions for operators and the cost/time efficiency of road maintenance. In this research, both technologies were experimentally assessed through mechanical properties, such as tensile and shear strength and demonstrated by repairing potholes previously created on testing slabs and subjected to wheel tracking tests. Furthermore, the innovative patching materials have been evaluated from energy consumption. Both methods obtained very satisfactory results, showing excellent durability much more similar to a new road than to a road repaired with current techniques frequently used.
