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.

  1. Sounds like a breakthrough if ever I've heard one. I think they could use something like this to alleviate some asphalt road repair in Minneapolis. It seems they can never get caught up.

  4. This is genius. These kinds of things always capture my interest. I'm going to look more into this and see if I can somehow use it for my driveway. It's either that or go with Pothole Specialist. My friend recently told me about them.

  6. Self healing asphalt? This stuff could really make a difference in the future. Who knew it was as easy as creating an abrasive compound that when run over collapsed into itself blunting the blow and energy. This is a great invention.

  7. What?! Self healing asphalt? That is crazy and I never thought that I would hear something like that in. That is crazy and I cannot wait to see this myself.

  8. Hmm... not sure if I'm buying into it. Would like to see this hold up somewhere with harsh seasons. It will be cool if it does work though!

  9. That is a great invention. Are the steel wool fibers expensive to put into the roads? How does the heating take place? Thanks for the article!

  10. This is amazing. It seems like asphalt is something that needs to be fixed constantly. I wonder if America will get this self healing asphalt anytime soon?

  11. I recently found out that asphalt could be recycled. Though it does make me curious to know how well the recycled asphalt lasts compared to that of brand new asphalt. There can be trade offs in things like quality to save money, but it shouldn't be to far off from the original quality.
