For a robust substructure of rails a sharp-edged gravel is needed. Due to the rail operation and the related continuous stress of the track bed, this gravel layer is weared out and loses its stabilising effect.
HARTSTEINWERKE Vogtland recycles this removed railway ballast. The fine fraction is separated from the usable rock. In a further processing step, quality-controlled substitute building materials are produced in accordance with the Substitute Building Materials Ordinance. The material is thus recycled and can be reused in high-quality building material mixtures.
HARTSTEINWERKE Vogtland uses asphalt granulates of recycling class A as part of antifreeze layers of various grains in several plants. This process, with the help of the recycled asphalt, contributes to relieve the own deposits and furthermore nevertheless to properly use granulates not needed for recycling in asphalt construction.
