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.

Interview on BNR newsradio (in Dutch)

A few weeks ago Gerbert van Bochove (Breijn-Heijmans) and Martin van der Ven (Delft University) were interviewed bij BNR newsradio (in Dutch) about the development of our self healing asphalt. A new test section is prepared by Heijmans in Tilburg (Netherlands), which is explained in the interview.
You can listen at the recording at the BNR-website.
