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.

RTL4 news item

RTL4 news had yesterday an item on road damage on Dutch highways. Self Healing Asphalt with steelwool was proposed as a possible solution. In the video you see some shots from the project in our lab.
RTL4 is a commercial TV station, which means you first have to watch a commercial before the video starts. Sorry about that.....
