Asphalt core heated with induction energy

At the right you can see an asphalt core with steelwool fibers that is heated op to 120 oC under the induction machine in the laboratory. The image is taken with our infrared camera.

CT-scan of new asphalt

To check the distribution of fibers in the asphalt we put some samples in our CT-scanner. This gives the nice images below.

Self Healing Asphalt on A58

Saturday December 11 was an important day for the self healing asphalt. The concept which is the outcome of the IOP project SHM0617 “Unravelling of Porous Asphalt” is used in a full scale application. On the Dutch highway A58 near Vlissingen a section of 400 meter had to be renewed. Rijkswaterstaat, always willing to try new inventions, offered the road to science. The self healing porous asphalt developed by the Microlab and the Road Engineering lab of the Civil Engineering faculty of Delft University was used. Contractor Heijmans, also partner in the IOP project, took care of making the asphalt and placing it on the road. Partner INTRON will take care of the healing process by using an induction machine to heat up the steelwool fibers that are placed inside the material. Alvaro Garcia and Erik Schlangen, members of the developers-team , went in spite of the cold weather to Zeeland to shoot some pictures.
