Calcined bauxite has traditionally been the most commonly used aggregate material used for High Friction Surfacing.The inherent nature of Calcined Bauxite resists shear stresses that lead to polishing of the road surface. Its hardness is also beneficial in internal and external industrial flooring applications where a very hard and long lasting mineral is required to give high-friction, anti-slip performance.Calcined Bauxite has been found to exhibit characteristics far superior to alternative road surface aggregates.
