Type examination of aggregates

Type examinations are carried out mainly on the basis of requirements stipulated in norm PN-EN 12620 aggregates for concrete, PN-EN 13242 aggregates for unbound and hydraulically bound materials for use in civil engineering work and road construction or PN-EN 13043 aggregates for bituminous mixtures and surface treatments for roads, airfields and other trafficked areas.

Among the basic requirement deriving from those norms you can find an analysis of granulometric content, determination of fluid content, petrographic description of aggregates, tests for  resistance to fragmentation or determination of sulphur and chloride content. It is important to classify aggregates to the correct usage in building industry and to implement correct type of type examination to documentation given to a customer.
