Induction Healing of Porous Asphalt

In order to elongate the life span of porous asphalt, Rijkswaterstaat is doing a technical trial with a new porous asphalt mixture in which steel _bres are mixed in the bitumen binder. This allows an in-situ rejuvenating heat treatment of the road surface by means of induction. In recent tests with the Roll Pave concept (speeding up resurfacing by application of prefabricated porous asphalt surfaces), the induction technique was demonstrated on the associated adhesive. Now the technology will be tested on the (prepared) binder itself. The trial is carried out in collaboration with TNO and the Technical University Delft.
