Asphalt production
Asphalt, the dominant construction material for our road network, is mainly produced from natural aggregates, i.e. powdered aggregate, sand and grits. As producers of aggregates and processors in our asphalt plants, we know what is important. In our quarries, we produce different aggregates for asphalt plants from the rocks diabase, greywacke and limestone, whether for asphalt concretes, stone mastic asphalt, mastic asphalt, porous asphalts or surface treatments.
