Did you know that the number of vehicles will remain stable over the next ten years and that the number of tires to be disposed of will remain constant? The well-known processes used for recycling, on the other hand, are changing - less and less thermal recycling is used.
In accordance with the circular economy, the aim is to recycle and reuse all raw materials. Tire grinding is a technology that makes an important contribution to this by producing technologically complex and high-quality rubber powder. Rubber modified asphalt is an excellent way to recycle the rubber powder.
Not only those who dispose of used tires know this, but also specialty chemical 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® can be processed without any problems and offers decisive advantages: less rutting, longer durability and, especially when laying porous asphalt, a significantly lower noise level.
In order to show the quality of the rubber-modified asphalt in use, the premises of SHORT in Wendlingen asphalted with rubber asphalt by the Kirchheim road builder Waggershauser. The project is also scientifically supported 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 of course it's a big step forward when we can show the advantages live right on our doorstep."
This project is now starting and we will show you exclusive insights into our Construction site diary!
