Bituminous mixtures - Test methods for hot mix asphalt - Part 4: Bitumen recovery: Fractionating column
This European Standard describes a test method for the recovery of soluble bitumen from bituminous mixtures from pavements in a form suitable for further testing. The procedure is suitable for the recovery of paving grade bitumen and is also suitable for mixtures containing volatile matter such as cutback bitumen but the results may be less precise. NOTE: There is limited experience of recovery when polymer-modified bitumen is used.
Asphalt - Prüfverfahren für Heißasphalt - Teil 4: Rückgewinnung des Bitumens: Fraktionierkolonne
Dieses Dokument legt ein Prüfverfahren fest, mit dem aus Asphalt, der als Straßenbaumaterial verwendet
wird, lösliches Bitumen in einer zur weiteren Prüfung geeigneten Form zurückzugewinnen ist. Dieses
Verfahren eignet sich zur Rückgewinnung von Straßenbaubitumen, es ist aber auch auf Mischgüter, die flüch-
tige Bestandteile enthalten, wie z. B. verschnittenes Bitumen, anwendbar; die bei diesen erhaltenen Ergeb-
nisse sind jedoch unter Umständen weniger präzise. Für Mischgüter, die flüchtige Bestandteile enthalten, ist
das in dieser Europäischen Norm angegebene Verfahren das Referenzverfahren, während das Verfahren mit
dem Rotationsverdampfer (siehe EN 12697-3) das Referenzverfahren für Mischgüter mit Straßenbaubitumen
ist.
ANMERKUNG Für die Rückgewinnung von polymermodifiziertem Bitumen liegen nur begrenzte Erfahrungen vor.

WARNING — The method described in this European Standard may require the use of
dichloromethane (methylene chloride), 1.1.1 trichlorethane, benzene, trichlorethylene, xylene, toluene
or other solvent capable of dissolving bitumen. These solvents are hazardous to health and are
subject to occupational exposure limits as detailed 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.

1 Scope
This document describes a test method for the recovery of soluble bitumen from bituminous mixtures from
pavements in a form suitable for further testing. The procedure is suitable for the recovery of paving grade
bitumen and is also suitable for mixtures containing volatile matter such as cut-back bitumen but the results
may be less precise. This European Standard is the reference method for mixtures containing volatile matter,
but the rotary evaporator procedure (see EN 12697-3) for mixtures with paving grade bitumen.
NOTE There is limited experience of recovery when polymer-modified bitumen is used.
2 Normative references
The following referenced documents are indispensable for the application of this document. For dated
references, only the edition cited applies. For undated references, the latest edition of the referenced
document (including any amendments) applies.
EN 12594, Bitumen and bituminous binders — Preparation of test samples.
EN 12697-1, Bituminous mixtures — Test methods for hot mix asphalt — Part 1: Soluble binder content.
EN 12697-3, Bituminous mixtures — Test methods for hot mix asphalt — Part 3: Bitumen recovery: Rotary
evaporator.
EN 12697-38, Bituminous mixtures — Test methods for hot mix asphalt — Part 38: Common equipment and
calibration.
3 Terms, definitions and symbols
For the purposes of this document, the following terms and definitions apply.
3.1
soluble binder content
percentage by mass of extractable binder in an anhydrous sample determined by extracting the binder from
the sample
NOTE Extraction may be followed by binder recovery.
3.2
insoluble binder content
percentage by mass of binder that adheres to the aggregate after extraction
3.3
precision
closeness of agreement between independent test results obtained under stipulated conditions
NOTE 1 Precision depends only on the distribution of random errors and does not relate to the true value or the
specified value.
NOTE 2 The measure of precision is usually expressed in terms of imprecision and computed as a standard deviation
of the test results. Less precision is reflected by a larger standard deviation.
NOTE 3 “Independent test results” means results obtained in a manner not influenced by any previous result on the
same or similar test object. Quantitative measures of precision depend critically on the stipulated conditions. Repeatability
and reproducibility conditions are particular sets of extreme conditions.
