Erik Schlangen: A "self-healing" asphalt

The video discusses the advantages and disadvantages of asphalt roads, focusing on noise and splash water issues. It introduces porous asphalt as a solution but highlights the problem of raveling. The concept of self-healing asphalt using steel wool and induction heating is presented as a solution to extend road life. Testing and real-world applications are discussed, with a demonstration showing the effectiveness of the technology.
