Polishing resistance of aggregates in aspect of its usage to wearing course road pavements

In 2008 Technical Requirements WT-1 (Standards WT-1 imposed a requirement to evaluate a polishing resistance of aggregate used for wearing course based on PSV ratio (Polished Stone Value) determined according to PN-EN 1097-8:2001. The paper present test results of PSV ratio of aggregates from 40 domestic and 3 foreign sources in relation to requirements of aggregates for wearing course. Bearing in mind the limited resources of aggregates that meet the criteria of required polishing resistance the results of aggregate mixes characterized with different PSV ratio were presented.
