Polished Stone Value - Test Procedures and Equipment

2015-10-17  For the majority of aggregates the impact value and the crushing value are similar, but brittle materials such as flints yield impact values which are about 5 units higher than their crushing values. The impact test is widely used as an alternative to the crushing test. Aggregate Abrasion Value

The Polished Stone Value of aggregates and in-service

At present, PSV (Polished Stone Value) is the only parameter relating to the microtexture properties of an aggregate which can be measured in a standardised manner and which has been related to traffic and site conditions. It therefore remains an appropriate property to use in specifications, provided that its limitations are recognised. Themes:
