POSSIBLE PROBLEMS WITH HIGH PSV AGGREGATE OF
POSSIBLE PROBLEMS WITH HIGH PSV AGGREGATE OF THE GRITSTONE TRADE GROUP. This paper considers the methods of assessment of high PSV (Polished Stone Value) greywacke aggregate from the Longford Down Massif. It reviews current specification requirements concluding that PSV is regarded as the most important surfacing aggregate property in the UK.
