Polished Stone Value (PSV) Test

Polished Stone Value (PSV) Test
The Polished Stone Value (PSV) Test measures aggregate surfaces' resistance to polishing under vehicular wear. This test, conducted in accordance with BS EN 1097-8, is particularly essential for aggregates used in surface layers of highways and runways where skid resistance is critical. Aggregates that polish too quickly may become smooth, increasing the danger of sliding and accidents. PSV testing enables for the selection of aggregates that preserve surface texture and grip, hence improving road safety over time. It is commonly employed in highway engineering, airport runway building, and any application that requires exposed aggregate surfaces.

Advantages of Polished Stone Value (PSV) Test

• Ensures long-term skid resistance.
• Improves road and runway safety.
• Identifies high-performance surface materials.
• Ensures conformity with road authority guidelines.
• Reduces the likelihood of traffic accidents on polished surfaces.
