Bituminous mixtures - Test methods for hot mix asphalt - Part 42: Amount of coarse foreign matter in reclaimed asphalt; English version of DIN EN 12697-42:2006-02
This document (EN 12697-42:2005) specifies a visual method of determining the amount and components of
coarse foreign matter in reclaimed asphalt. This method does not completely categorise the foreign matter
that can occur in asphalt
NOTE 1 For the use of reclaimed asphalt in asphalt mixtures, it is important to know the components in the reclaimed
asphalt and to what extent coarse foreign matter is present that can influence the properties of the asphalt mix.
NOTE 2 The method is not intended to categorise all foreign materials but rather to ensure that the amount of coarse
foreign materials are minimised.
