Stone Mastic Asphalt is a polymer modified hot bituminous mixture with a large portion of coarse aggregate and rich bitumen-filler mastic. The advantages of Stone Mastic Asphalt include:
  High rut resistance and stability due to aggregate skeleton
  Better skid resistance due to large macro texture
  Increased durability and improved ageing properties due to thicker bitumen coating
  Reduced water spray and better visibility
  Reduced traffic noise
