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 Materials on Dutch TV
If you would like to know more about self healing materials you should watch the TV-program "HET KLOKHUIS" tomorrow evening on the "Nederland 3" from
18:25 to 18:40. They will show the development of Self Healing Polymers
for more info look at the site of AgentschapNL
or look at the site of "Het Klokhuis". There you can also watch it on internet later, in case you missed it.

CT-scan of new asphalt
To check the distribution of fibers in the asphalt we put some samples in our CT-scanner. This gives the nice images below.

Self Healing Asphalt on A58
Saturday December 11 was an important day for the self healing asphalt. The concept which is the outcome of the IOP project SHM0617 “Unravelling of Porous Asphalt” is used in a full scale application. On the Dutch highway A58 near Vlissingen a section of 400 meter had to be renewed. Rijkswaterstaat, always willing to try new inventions, offered the road to science. The self healing porous asphalt developed by the Microlab and the Road Engineering lab of the Civil Engineering faculty of Delft University was used. Contractor Heijmans, also partner in the IOP project, took care of making the asphalt and placing it on the road. Partner INTRON will take care of the healing process by using an induction machine to heat up the steelwool fibers that are placed inside the material. Alvaro Garcia and Erik Schlangen, members of the developers-team , went in spite of the cold weather to Zeeland to shoot some pictures.
