Germany // Sengenthal (Bavaria)
Ready for asphalt production of the future: The new BA RPP 4000 operated by the Max Bögl Group is something special. The plant is installed at the Sengenthal site and supplies around 2,000 t of asphaltic mixtures to construction sites across the region every single day. Depending on the formula, the supplied mixture can contain around 1,800 t of RAP. That is because the recycling innovation from BENNINGHOVEN, which consists of a counterflow parallel drum system with a hot-gas generator, can achieve RAP material rates of 90 + X %. This unique technology also massively reduces emissions at the same time, making investment in this green and efficient technology particularly sustainable and forward-looking. In industrialized nations such as Germany, it has long been the case that many more miles of road are renovated than built from new – which means that millions of metric tons of asphalt are also removed. This task is largely handled by cold milling machines, which at their maximum performance level can load up to 3,000 t of milled material onto trucks in a single shift. This waste asphalt has long posed a challenge for road construction companies.
