Bituminous mixtures - Test methods - Part 35: Laboratory mixing
This European Standard describes the laboratory mixing of bituminous materials for the manufacture of specimens. The standard specifies the reference compaction temperatures for mixing based on the grade of the binder for paving grade and hard paving grade bitumen.
Annex A describes the method for manufacture of samples of asphalt mixtures using foamed bitumen.
Annex B describes the method for manufacture of samples of asphalt mixtures using bitumen emulsion.
Once mixed, mastic asphalt samples are prepared in accordance with Annex C.

Anhang A beschreibt das Verfahren zur Herstellung von Proben aus Asphalt mit Schaumbitumen.
Anhang B beschreibt das Verfahren zur Herstellung von Proben aus Asphalt mit Bitumenemulsion.
Nach dem Mischen werden Gussasphaltprobekörper nach Anhang C hergestellt.
Mélanges bitumineux - Méthodes d'essais - Partie 35: Malaxage de laboratoire
La présente Norme européenne décrit le mélange de matériaux bitumineux en laboratoire dans le cadre de la fabrication d'éprouvettes. Elle définit les températures de mise en oeuvre de référence pour le mélange en fonction du grade du liant routier.
L'annexe A décrit la méthode de fabrication des mélanges bitumineux à base de mousse de bitume.
l’annexe B décrit la méthode de préparation des mélanges bitumineux a base d'émulsion ;
Une fois malaxées, les éprouvettes d'asphalte coulé doivent être préparées conformément à l'Annexe C.
Bitumenske zmesi - Preskusne metode - 35. del: Laboratorijska zmes
Ta evropski standard opisuje laboratorijske zmesi iz bitumenskih materialov za izdelavo vzorcev. Standard določa referenčne inštalacijske temperature za zmesi na podlagi cestnogradbenih lastnosti veziva.
Za asfaltne zmesi, pri katerih se uporabljajo penasti bitumen ali bitumenske emulzije, se uporablja dodatek A ali točka A.5.6.
Po izdelavi zmesi je treba pripraviti vzorce litega asfalta v skladu s točko B.3.

European foreword
This document (EN 12697-35:2016) has been prepared by Technical Committee CEN/TC 227 “Road
materials”, the secretariat of which is held by DIN.
This document supersedes EN 12697-35:2004+A1:2007.
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 October 2016, and conflicting national standards shall
be withdrawn at the latest by October 2016.
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.
Compared with EN 12697-35:2004+A1:2007, the following changes have been made:
a) Title changed to allow inclusion of asphalt produced at lower temperatures;
b) Annex A (normative) added for the manufacture of samples of asphalt with foamed bitumen;
c) Annex B (normative) added for the manufacture of samples of asphalt with bitumen emulsion;
d) Annex C (normative) added for the manufacture of samples from mastic asphalt;
e) introduction of formula for super-heating aggregate when significant proportions of reclaimed
asphalt are used;
f) “Target mixing temperature” extended to “target laboratory mixing temperature” and used
throughout the document;
g) introduction of the term “Reference compaction temperature”;
h) determination of reference compaction temperature in 6.1 extended, including an allowance to
reduce it for asphalt mixtures designed to be produced at lower temperatures;
i) the term “pen” removed from units in Table 1;
j) the time to reach mixing temperature in 6.2.4 changed;
k) “RAP” changed to “reclaimed asphalt” in 6.3;
l) the option to defer adding the filler in 6.5.3 extended to allow deferring adding the fine aggregate as
well or instead;
m) added requirement for addition of cold reclaimed asphalt to the mixer;
n) adjusted scope to be in line with text in Table 1.
