Drumurile pavate sunt frumoase, dar se strică repede, iar reparațiile sunt costisitoare.  Erik Schlangen demonstrează un nou tip de asfalt  făcut din materiale simple cu caracteristici uimitoare: când crapă pot fi reparate prin încălzire inductivă. (Filmat la TEDxDelft.)

Erik Schlangen: Asfalt care se repară singur

Porous asphalt makes roads quieter and safer, but it is prone to damage like raveling and potholes. By mixing tiny pieces of steel wool into the asphalt, engineers can use induction heating to melt the binder and repair micro-cracks, restoring the road’s surface. This method was tested on a 400-meter stretch of Dutch highway and doubled the surface lifespan. The approach promises to save significant money and reduce roadwork disruptions.
