Germany // Sengenthal (Bavaria)
Ready for the asphalt production of the future: the new BA RPP 4000 operated by the Max Bögl Group is something special. Located in Sengenthal, the plant supplies some 2,000t of hot mix to job sites across the region every single day. Depending on the formula, about 1,800t of the mixes can consist of RAP. That is because the recycling innovation from BENNINGHOVEN, the counterflow parallel drum system with hot gas generator, can work with RAP material rates of 90 + X %. The unique technology also delivers a massive reduction in emissions, making investment in this green and efficient technology particularly sustainable and forward-looking. After all, in industrialized nations such as Germany it has long been the case that far more miles of road are rehabilitated than built from new – which also means that millions of tonnes of asphalt are removed. This task is largely handled by cold milling machines, which at their peak can load up to 3,000t of milled material onto lorries in a single shift. The residual waste from such operations has long posed a challenge for road construction contractors.
