Polished Stone Value Test Procedures and Equipment

The Polished Stone Value of aggregate gives a measure of resistance to the polishing action of vehicle tyres under conditions similar to those occurring on the surface of a road. The action of road vehicle tyres on road surfaces results in polishing of the top, exposed aggregate surface, and its state of polish is one of the main factors

Rock Aggregates and Its Suitability Geology

This is assessed by measuring aggregate abrasion value and polished stone value. Aggregate abrasion value (AAV) measures the resistance to surface wear by abrasion. The lower the value, the greater is the resistance. ADVERTISEMENTS: Many regulations recommend a value less than 8 for general road use. Polished stone value
