Current asphalt roads already have self-healing properties, but they require long rest times. To accelerate this self-healing process we need high temperature. To create this high temperature we add steel fiber to our asphalt mixture because it conducts heat 106 times better than asphalt.

The machine uses induction heating to accelerate the heating process asphalt. It is used by driving over our steel fiber asphalt. Induction heating involves the process of using a magnet to rapidly heat up a metal (in our case steel fibers). This happens by using an induction machine to drive over the asphalt. In the process it involves sending an electric current through a series of coils, resulting in a magnetic field. The magnetic field heats up molecules within a ferromagnetic metal (a substance that is highly susceptible to magnetization)- in this case, the steel fibers.

This machine is applied over roads every 2-4 years.

The induction machine costs $500,000 and the asphalt costs $120 per tonne.

Our solution is based of the researcher at Delft University of Technology, Wuhan University of Technology, University of Nottingham, Worcester Polytechnic Institute, Iran University of Science and Technology, and University of Granada.

With our induction machines and steel fiber asphalt we can make roads last 2x more than current roads.
