2017-4-1  High Polished Stone Value (hPSV) aggregates are a valuable resource in the manufacture of skid-resistant surfaces (pavements). Previous studies have tried to define the essential properties required within a specific rock type that makes it suitable as hPSV aggregate. There are also quantitative tests that can assign a standardised value to the polishing resistance of each aggregate (PSV or ...
