test on road aggregates by crushing value test

  • Aggregate tests northstonematerials.com

    Polished stone value ( PSV ) – This is a most important test that an aggregate can undergo if it is to be used as a road surface course. If an aggregate polishes too much under the polishing effect of vehicle tyres, the road surface becomes very slippery, especially when wet, and the number of skidding accidents can increase.
