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.

Self Healing Materials

More info on all types of self healing materials can be found on the website of the AgentschapNL and the website of DCMat (Delft Centre for Materials).

If you want to read more about these projects you can also download this nice booklet.

and this is the 2nd edition of the booklet:

Did you know that:

  • we also are working on a self healing concrete using Bacteria
  • we make concrete stronger by using a sort of toothpaste
  • we are encapsulating cement to improve the self healing capacity of concrete
  • we are making capsules filled with rejuvenator to give asphalt a second life
