Bituminous mixtures - Test methods for hot mix asphalt - Part 42: Amount of foreign matter in reclaimed asphalt

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.

Asphalt - Prüfverfahren für Heißasphalt - Teil 42: Fremdstoffgehalt in Ausbauasphalt

Diese Europäische Norm legt ein Sichtprüfverfahren zur Bestimmung des Gehalts an groben Fremdstoffen in Ausbauasphalt und deren Bestandteile fest. Ein Verfahren zur Bestimmung des Gehalts an feineren Fremdstoffen in Ausbauasphalt und deren Bestandteile wird in Anhang A angegeben. Dieses Verfahren ist nicht dazu geeignet, die Fremdstoffe, die in Asphalt enthalten sein können, vollständig zu klassifizieren. ANMERKUNG 1 Für die Verwendung von Ausbauasphalt in Asphaltmischgütern ist es wichtig zu wissen, welche Be-standteile im Ausbauasphalt enthalten sind, und die Mengenanteile der groben Fremdstoffe zu kennen, die die Eigen-schaften des Asphaltmischgutes beeinflussen können. ANMERKUNG 2 Das Verfahren ist nicht dazu bestimmt, alle Fremdstoffe zu klassifizieren, sondern sicherzustellen, dass der Gehalt an groben Fremdstoffen auf ein Mindestmaß reduziert wird.

Mélanges bitumineux - Méthodes d'essai pour mélange hydrocarboné à chaud - Partie 42: Quantité de matériaux étrangers présents dans les agrégats d'enrobés

La présente Norme européenne spécifie une méthode visuelle permettant de déterminer la quantité et les
composants de matériaux étrangers grossiers dans les agrégats d'enrobés. Une méthode visant à déterminer
la quantité et les composants de matériaux étrangers grossiers dans les agrégats d'enrobés est fournie à
l'Annexe A. Cette méthode ne permet pas de classer en catégories la totalité des matériaux étrangers
susceptibles d'être présents dans les enrobés.
NOTE 1 En vue de l'utilisation d'agrégats d'enrobés dans les mélanges bitumineux, il est important de connaître les
composants de ces agrégats et de savoir dans quelle proportion sont présents les matériaux étrangers grossiers qui
peuvent influer sur les propriétés du mélange bitumineux.
NOTE 2 La méthode n'est pas destinée à classer en catégories la totalité des matériaux étrangers, mais à s'assurer
que la quantité de matériaux étrangers grossiers est aussi faible que possible.

Bitumenske zmesi - Preskusne metode za vroče asfaltne zmesi - 42. del: Vsebnost nečistoč v asfaltnem granulatu

Ta evropski standard podaja vizualno metodo za določanje količine in sestavin surovih nečistoč v ponovno uporabljenem asfaltu. Metoda za določanje količine in sestavin finejših nečistoč v ponovno uporabljenem asfaltu je podana v dodatku A. Ta metoda nečistoč, ki se lahko pojavijo v asfaltu, ne kategorizira popolnoma.

Asphalt - Prüfverfahren für Heißasphalt - Teil 42: Fremdstoffgehalt in Ausbauasphalt This European Standard was approved by CEN on 13 October 2012.
CEN members are bound to comply with the CEN/CENELEC Internal Regulations which stipulate the conditions for giving this European Standard the status of a national standard without any alteration. Up-to-date lists and bibliographical references concerning such national standards may be obtained on application to the CEN-CENELEC Management Centre or to any CEN member.
This European Standard exists in three official versions (English, French, German). A version in any other language made by translation under the responsibility of a CEN member into its own language and notified to the CEN-CENELEC Management Centre has the same status as the official versions.
CEN members are the national standards bodies of Austria, Belgium, Bulgaria, Croatia, Cyprus, Czech Republic, Denmark, Estonia, Finland, Former Yugoslav Republic of Macedonia, France, Germany, Greece, Hungary, Iceland, Ireland, Italy, Latvia, Lithuania, Luxembourg, Malta, Netherlands, Norway, Poland, Portugal, Romania, Slovakia, Slovenia, Spain, Sweden, Switzerland, Turkey and United Kingdom.

EN 12697-42:2012 (E) 3 Foreword This document (EN 12697-42:2012) has been prepared by Technical Committee CEN/TC 227 “Road materials”, the secretariat of which is held by DIN. This European Standard shall be given the status of a national standard, either by publication of an identical text or by endorsement, at the latest by May 2013, and conflicting national standards shall be withdrawn at the latest by May 2013. Attention is drawn to the possibility that some of the elements of this document may be the subject of patent rights. CEN [and/or CENELEC] shall not be held responsible for identifying any or all such patent rights. This document supersedes EN 12697-42:2005.
Compared with EN 12697-42:2005, the following significant changes have been made: — definition of coarse foreign matter includes 8 mm minimum size; — solvent for hydrocarbons made less specific; — classifications for material brought directly into line with those in EN 13108-8; — source of reclaimed asphalt to be reported clarified; — annex for analysis of finer material added. WARNING — The methods described in this European Standard require the use of solvents that are hazardous to health and are subject to occupational exposure limits as described in relevant legislation and regulations. Exposure levels are related to both handling procedures and ventilation provision and it is emphasised that adequate training should be given to staff employed in the usage of these substances.
