Asphalt Additive Duroflex® - Eco

Since 2017, we have included a further development of Duroflex®, which has been tried and tested for years, and will be made available to the customer from now on. Duroflex® - Eco, which was called the working title Duroflex® - Super 140 during the development phase, allows the temperature of the asphalt mixing process to be converted 10 ° C ... .20 ° C during the production of mastic asphalt (SMA).

The use of soft and economical bitumen grade 50 or grade 70 is possible. As a result, the much more expensive polymer-modified bitumen (PMB) can be substituted.

The reduction of the temperature of the asphalt mixing process is not only cost effective because of the associated energy saving, but it is also a contribution to reducing the climate-damaging CO2 emissions.

By reducing the grain size of the Duroflex® - Eco granulate, even more precise dosing is possible. The application and the technological parameters of the asphalt generation are similar to the other Duroflex® variants.

Duroflex® - Eco granulates are delivered in big bags per 1,000 kg.

That goes for our proven standard asphalt additive, Duroflex®-Eco, too. Improvement was made possible by the fact that all the ingredients that go into Duroflex ®-Eco have a different and an especially function. This means that they are evenly distributed in the asphalt, ensuring full effectiveness.


The new Duroflex ®-Eco, comes in granulate with a diameter from 4 mm, allowing them to be processed faster and more accurately by all commercially available dosing plants and dosing technologies. New Duroflex ®-Eco makes possible to reduce the asphalt mixing temperature, especially from SMA under use from a bitumen grade 50 or grade 70, down to 150 °C ….160 °C. Thanks Duroflex ®-Eco it’s possible to reduce the energy need, expenses and CO2- emission.
