DIN EN 1097-8-2009 骨料的机械和物理特性试验.第8部分:石料磨光值的测定,德文版本EN 1097-8:2009
Tests for mechanical and physical properties of aggregates - Part 8: Determination of the polished stone value; English version of DIN EN 1097-8:2009-10
This Standard describes the reference method used for type testing and in cases 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 may be used provided that an
appropriate working relationship with the reference method has been established.
Annex A describes an optional method for the determination of the aggregate abrasion value (AAV).
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, are required.
