▸ High PSV calcined bauxite engineered for anti-skid and high friction road surfacing applications worldwide.
★ High PSV 70+ ★ Al₂O₃ 75-90%
★ Low Aggregate Abrasion ★ High Friction Surfacing
▸ 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, significantly improving road safety and reducing accident rates.
▸ Our high PSV calcined bauxite delivers critical performance advantages for high friction surfacing:
Exceptional Skid Resistance — polished stone value (PSV) of 70 minimum provides long-lasting anti-skid performance, far exceeding conventional aggregates.
Low Aggregate Abrasion Value — AAV of 10 maximum ensures minimal wear under heavy traffic, maintaining surface friction for years.
High Hardness (7.5-9.0 Mohs) — angular grains resist polishing and retain micro-texture even under sustained traffic.
Proven Worldwide — specified by highway authorities and used in high friction surfacing systems across Europe, North America, and Asia.
▸ XRF Chemical Analysis — every batch tested for Al₂O₃, Fe₂O₃, TiO₂, CaO, MgO content
▸ PSV Testing — polished stone value tested in accordance with BS EN 1097-8 standards
▸ AAV Testing — aggregate abrasion value per BS EN 1097-8 to ensure maximum wear resistance
▸ Particle Size Distribution — sieve analysis for accurate 0-1mm, 1-3mm, and 3-5mm grading
▸ Batch Traceability — full documentation from raw ore to final shipment
