Calcined bauxite has traditionally been one of the most commonly used aggregate materials for High Friction Surfacing Treatment (HFST). HFST Bauxite is a high-alumina, calcined bauxite aggregate designed to provide excellent skid resistance, durability, and long-term surface performance for roads, highways, intersections, ramps, bridges, and other high-risk traffic locations.
| Sr. No. | Parameter | Specification |
|---|---|---|
| 1 | Al2O3 | 85% to 88% |
| 2 | SiO2 | 4% to 6% |
| 3 | TiO2 | 4% to 5% |
| 4 | Fe2O3 | 3% to 5% |
| 5 | LOI | 0.5% |
| 6 | BD | 3.1 to 3.2 |
High alumina content ranging from 85% to 88%.
Excellent skid resistance for improved road safety.
High durability and resistance to aggregate polishing.
Suitable for High Friction Surfacing Treatment applications.
High-density aggregate with bulk density of approximately 3.1 to 3.2.
Low loss on ignition (LOI) of approximately 0.5%.
HFST Bauxite is primarily used as a high-friction aggregate in road surfacing systems where enhanced traction and skid resistance are required.
Calcined bauxite is valued for its high hardness, durability, and resistance to polishing. These characteristics allow the aggregate to maintain a textured surface and provide reliable tire grip over extended service periods. It is therefore widely used in applications where maintaining adequate friction is important for vehicle control and road safety.
Our HFST Bauxite is produced from selected bauxite and processed through controlled calcination to achieve the required chemical composition and physical properties. The material is processed and supplied according to application requirements, including suitable aggregate grading and sizing for high-friction surfacing applications.
HFST Bauxite is calcined bauxite aggregate used in High Friction Surface Treatment systems. Its high alumina content, hardness, and durability make it suitable for applications requiring enhanced skid resistance and surface friction.
The specified Al2O3 content of our HFST Bauxite is 85% to 88%.
HFST Bauxite is used for high-friction road surfacing, including highways, intersections, ramps, bridge decks, sharp curves, steep grades, and other locations where increased surface friction is required.
The main benefits include high skid resistance, good durability, resistance to polishing, high alumina content, and suitability for demanding high-friction surfacing applications.
HFST Bauxite can be processed into suitable aggregate gradings and particle sizes depending on the requirements of the surfacing system and project specifications.
Please contact our sales team for detailed technical specifications, available grades and sizes, packaging options, material samples, and commercial quotations.
The combination of high Al2O3 content, controlled silica and iron oxide levels, low LOI, and high bulk density makes calcined bauxite a suitable aggregate for demanding high-friction surfacing applications.
