EVS-EN 1097-8:2000

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