Calcined Bauxite for high friction surface coating
Calcined bauxites originate from China or Guyana and are aggregates formed from aluminium ore which has been subjected to calcination, a heat treatment process. When calcined, Bauxite has exceptional physical hardness and stability, leading to excellent resistance to abrasion caused by the vehicle's tyres and a high resistance to polishing making it ideal for HFS applications.
*What is high friction surfacing?
High Friction Surface Treatment (HFST) is a cost-effective approach to address areas on roadways, such as horizontal curves, intersections or bridges, that demand higher friction in order to reduce vehicle skidding and save lives. The application process requires broadcasting the aggregate either by hand or mechanical method to the pavement surface using a polymer binder. Studies have shown that improving the friction by using HFST reduces crashes by 50-100%.
