This European Standard specifies the method for determining the polished stone value (PSV) of a coarse aggregate used in road surfacings. An optional method for the determination of the aggregate abrasion value (AAV) which gives a measure of the resistance of the aggregate to surface wear by abrasion under traffic is specified in Annex A. NOTE:The AAV method should be used when particular typ es of skid resistant aggregates (typically those with a PSV of 60 or greater) which can be susceptible to abrasion under traffic, are required.
