Did you know that the vehicle population will remain stable over the next ten years and the amount of tyres to be disposed of will remain constant? The known processes used for recycling, on the other hand, are changing - less and less is being recycled thermally.
Entsprechend der Kreislaufwirtschaft ist es Ziel, alle Rohstoffe zu verwerten und wieder zu verwenden. Die Reifenvermahlung ist eine Technologie, die dazu einen wichtigen Beitrag leistet, indem technologisch aufwendiges und hochwertiges Rubber powder hergestellt wird. Rubber-modified asphalt is an excellent way of recycling the rubber powder.
Not only waste tyre disposal companies are aware of this, but also specialty chemicals companies such as Evonik, which conducts research in this field and produces the additives required for processing, such as "VESTENAMER®". Relevant studies show that rubber asphalt with the additive "VESTENAMER®" is easy to process and offers decisive advantages: less rutting, longer durability and, especially when laying porous asphalt, significantly less noise.
To demonstrate the quality of the rubber-modified asphalt in use, the premises of KURZ in Wendlingen asphalted with rubberised asphalt by the Kirchheim road builder Waggershauser. The project is also being scientifically monitored by the engineering company PTM Dortmund. "We are investing a lot of money in the future here. It would have been easier to cover the company premises with "normal asphalt"," explains Hanna Schöberl, "but it is of course a big step forward when we can show the benefits live right on our doorstep."
This project is now starting and we will show you exclusive insights in our Building diary!
