This European Standard describes the reference method used for type testing and in case of dispute for determining the polished stone value (PSV) of a coarse aggregate used in road surfacings. For other purposes@ in particular factory production control@ other methods are possible provided that an appropriate working relationship with the reference method has been established. Examples of advanced test methods can be found in the Bibliography. Annex A describes an optional method for the determination of the aggregate abrasion value (AAV). NOTE 1 The AAV method is suitable to use when particular types of skid resistant aggregates@ (typically those with a PSV of 60 or greater) which can be susceptible to abrasion under traffic@ are required. The sample is taken from normal run of production from the plant. NOTE 2 Chippings that have been freshly crushed in the laboratory or recovered from bituminous materials may give misleading results.
