Surface treatment for traffic areas

Surface treatments are used for the maintenance and repair of traffic areas. This includes the spraying of bitumen, and the spreading of high-quality chippings.

  • Surface treatments offer the following advantages:
  • Sealing of the road surface
  • Increased grip
  • Reduced occurrence of water spray
  • Longer effectiveness of de-icing salts

Generally, the gravel should only consist of crushed hard rock which is resistant to abrasion, impact and polishing. RÖHRIGgranit® gravel has an exceptionally good bitumen affinity for granodiorite. A non-slip and bright coating is achieved. In addition, the very good impact resistance value (SZ value) deserves to be highlighted.
