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.

Breijn Symposium

Breijn is organising a symposium series this month about "Flexibilitiet in Levensduur"
Erik gave a presentation on Self Healing Materials yesterday. Last week Prof Sybrand van der Zwaag of Aerospace Engineering  of TU Delft was the guest speaker and next week Prof Andre de Boer from TU Twente will take the floor. More info on the symposium can be found on the Breijn-website.

Main topic of the presentation was Self Healing Concrete and Asphalt.
The Self Healing Asphalt part was dealing with the subject on this blog.
More info on the Self Healing Concrete projects can be found on

At the end of the symposium all participants received the Self Healing Breijn-Cube. Guess what kind of material this is?.....

  1. This looks like a really cool method of paving. It's difficult to keep a road looking nice for very long. That's especially true when there's a lot of traffic and/or freezing and thawing that go on. This would be a really good product for cities and states to keep the roads nice. I'd imagine it would be appealing for people with driveways as well.
