There has been a steady increase in mechanical loads applied to road surfaces in the global highway sector. This stems from a combination of increasing traffic volumes, plus heavier trucks. To prevent roads from cracking up under the strain, it has required the development of innovative new asphalt mixes able to cope with the increased mechanical loads. As a result, the research sector and the asphalt producers have been working together to develop special asphalt mixes, which often require special material

A German contractor is now using the innovative BA RPP 4000 asphalt mixing plant from Benninghoven to boost efficiency. The firm, Max Bögl, is using the plant at its Sengenthal site, to supply material to road construction projects in the Nuremberg region. A key feature of the plant is the hot gas generator with counterflow parallel drum system, which allows high RAP content and minimal emissions. The plant supplies some 2,000tonnes/day of hot mix to job sites across the region. Depending on the formula,
