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 Conference Bath

End of June we had a very interesting conference in Bath UK about self healing materials.
A lot of new research was presented and many good ideas for furthure work were proposed.
Below you see all the participants:

Erik presented the work on the self healing road. It turned out that this was one of the first real application (and maybe the only one...) of a civil engineering self healing material.
