Self Healing Aspalt on the A58

On this Blog we will give info on the test track with Self Healing Asphalt that is built on the A58 near Vlissingen in The Netherlands. The Asphalt is a special type of ZOAB (very porous aphalt concrete) containing small steelwool fibres. A known but serious problem with ZOAB is ravelling: stones at the surface coming off in time due to microcracking in the binder. The special ZOAB that is developed at Delft University (sponsored by AgentschapNL) can be heated with induction energy due to the fibres that are present which closes the microcracks and with that extends the service life of the road.

Erik performs at TEDx Delft

Yesterday Erik gave a presentation on self healing asphalt at TEDx-Delft.

You can watch the presentation on the TEDx-Delft page.


  1. I read your blogs regularly. Your humoristic way is amusing, continue the good work!

  2. I love this video. I will consider this when doing asphalt repair in Seattle. Thanks.

  3. This is crazy stuff, I can't believe it works that well! I wonder if there are any drawbacks to self-healing asphalt. If not, I'm sure that a lot of asphalt companies will adopt some form of self healing asphalt for civil works and such.

  4. I watched it afterwords online. That is some incredible technology. It's strange to think about driving on such malleable material. I hope self-healing asphalt becomes a national reality sooner rather than later! Thiago |

  5. Self healing asphalt could certainly prove useful in the more rural roads that aren't allowed the privileged of upkeep all that often. I think that the concept of such a road is down right marvelous to say the least. It would be so nice to know that our roads are capable of self preservation to some degree.
