- In terms of production, no. In production, selected buffing dusts were mixed with special basic bitumens and brought to reaction. (temperature / time). In terms of production, a so-called wet process. Only in a further production process, under the addition of bulking agents and further additives and inhibitors, was the rubber/bitumen mixture granulated. It is now available as a granulate and can be viewed as a dry process in terms of handling.
CTS, based in Buch am Erlbach, Bavaria (Germany), has been involved in the development and improvement of rubber-modified bitumen for road construction since 1985. Among other things, we developed porous asphalt into "Flüsterasphalt®". As one of the first market participants in the field of rubber modification, we claim to be the technology leader today. After many years of research and continuous development, CTS Bitumen was able to present an absolutely innovative new development: rubber-modified bitumen granulates. This achievement sets new standards and is characterised worldwide by unproblematic handling, transport and above-average performance.
