The bitumen binders used in asphalt are playing a crucial role for the performance of the asphalt. Today, 25% of the binders are polymer modified bitumen (PmB), providing a more sophisticated performance and a wider temperature range than pure bitumen does. The future share of PmB is likely to grow due to environmental regulations, due to a higher quote of recycling asphalt and due to requests for lower temperature processing e.g. for air port run  ways
