Bituminous mixtures - Test methods for hot mix asphalt - Part 42: Amount of foreign matter in reclaimed asphalt
|Publication Date:||1 November 2012|
|ICS Code (Road construction materials):||93.080.20|
This European Standard specifies a visual method of determining the amount and components of coarse foreign matter in reclaimed asphalt. A method for determining the amount and components of finer foreign matter in reclaimed asphalt is given in Annex A. 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.
