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.

mechanism of raveling
The picture below gives a schematic represenation of raveling:
how does ice and snow effect this material? What about the snow removal vehicles, do the trucks deterioate this material any faster than standard asphalt?
The ZOAB (very porous asphalt concrete) is used at 90% of het highways in the Netherlands, because of its excellent properties in noice reduction and (splash) water drainage. However the durability is lower than mormal dense asphalt. Snow, ice and traffic loading does not help indeed. With the proposed method of adding steelwool fibers and heating them with induction we hope to get bring this material to the same level as the dense asphalt as far as service life is concerned.

The mechanism of raveling is a fascinating process that plays a critical role in various materials, particularly in textiles and fibers. It involves the unravelling of yarns and fabrics, often leading to structural weaknesses. Understanding this mechanism is essential for improving product durability and performance. For those interested in learning more about the effects of raveling on different materials, check out fleetsworld for in-depth discussions and insights into textile engineering and related fields.
The mechanism of raveling refers to the gradual disintegration of pavement as the top layer loses aggregate, usually due to weakened binder or insufficient compaction. This process can lead to severe road damage if not addressed promptly. If you're studying topics like this and need assistance with balancing your academic load, you can always take my ged test and get expert help to ensure you succeed in all areas.
