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.

Test with induction machine!

In June 2014 we did a test with the prototype of the induction machine on the test-track on the A58 near Vlissingen. The result of this tests are very promising,
Below you see an image taken with an infrared camera during the test:


  1. Nice information shared here. One can also get the details of steel fibres for concrete only at Precision Drawell.

  2. Excellent blog shared. If anyone looking for steel fiber then you can contact Precision Drawell. Thanks for sharing.
