What Is High PSV Calcined Bauxite?

▸ High PSV calcined bauxite is a premium refractory-grade aggregate produced by calcining selected raw bauxite at temperatures above 1600°C. Its exceptional Polished Stone Value (PSV ≥70) and high resistance to abrasion make it the material of choice for high friction surfacing (HFS) on highways, bridge decks, airport runways, and other critical traffic areas.

▸ The angular particle shape and extreme hardness ensure long-lasting skid resistance, even under heavy traffic loads and harsh weather conditions.

▸ Widely specified by highway authorities and used in high friction surfacing systems across Europe, North America, and Asia, it significantly improves road safety and reduces accident rates.

Production Process

▸ Selected raw bauxite → High-temperature calcination (≥1600°C) → Crushing → Precision screening → Final inspection & packaging

▸ From bauxite ore to finished sand, every stage is controlled to ensure consistent quality:
