Bitumen and bituminous binders - Determination of equi-shear modulus temperature and phase angle using a Dynamic Shear Rheometer (DSR) - BTSV test
This document specifies the Binder Fast Characterization Test (for short: BTSV test, German: Bitumen-Typisierungs-Schnell-Verfahren). The test is conducted using a Dynamic Shear Rheometer (DSR). It is used to quickly characterize bitumen and bituminous binders and to assess the deformation behaviour at high service temperatures.
This document deals with the testing of fresh paving grade bitumen and modified bitumen, as conditioned in a laboratory ageing procedure (e.g. EN 12607 1, EN 14769) and also as recovered from asphalt mixtures. The test procedure in accordance with this document is not applicable for bituminous binders with particles larger than 250 μm (e.g. filler material, granulated rubber).
NOTE The test procedure has not been applied on bituminous binders recovered from bitumen emulsions yet.
The test determines the temperature and the associated phase angle at which a bituminous binder exhibits a defined complex shear modulus in stress-controlled oscillation mode at constant frequency and with continuous increase of the test temperature.
WARNING — The use of this document can involve hazardous materials, operations and equipment. This document does not purport to address all of the safety problems associated with its use. It is the responsibility of the user of this document to establish appropriate safety and health practices and to ensure that regulatory requirements are fulfilled prior to application of this document.
Bitumen und bitumenhaltige Bindemittel - Bestimmung der Äqui-Schermodultemperatur und des Phasenwinkels im Dynamischen Scherrheometer (DSR) - BTSV-Prüfung
Dieses Dokument legt das Bitumen Typisierungs Schnell Verfahren (kurz: BTSV Prüfung) fest. Die Prüfung wird im Dynamischen Scherrheometer (DSR) durchgeführt. Sie dient der schnellen Typisierung von Bitumen und bitumenhaltigen Bindemitteln sowie der Beurteilung des Verformungsverhaltens bei hoher Gebrauchstemperatur.
In diesem Dokument wird die Prüfung von frischem Straßenbaubitumen und modifiziertem Bitumen sowohl in einem im Laboratorium gealterten (z. B. EN 12607 1, EN 14769) als auch in einem aus Asphaltmischgut rückgewonnenen Zustand behandelt. Für bitumenhaltige Bindemittel mit Partikeln (z. B. Füllstoffe, Gummigranulat) größer 250 μm ist das Prüfverfahren nach diesem Dokument nicht anwendbar.
ANMERKUNG Das Prüfverfahren wurde bisher noch nicht auf bitumenhaltige Bindemittel angewendet, die aus Bitumenemulsionen rückgewonnen wurden.
In der Prüfung wird die Temperatur und der zugehörige Phasenwinkel ermittelt, bei der/dem ein bitumenhaltiges Bindemittel im spannungsgeregelten Oszillationsmodus bei konstanter Frequenz und stetiger Zunahme der Prüftemperatur einen definierten komplexen Schermodul aufweist.
WARNUNG — Die Anwendung dieses Dokumentes kann die Anwendung gefährlicher Stoffe, Arbeitsgänge und Geräte mit sich bringen. Dieses Dokument beansprucht nicht, alle damit verbundenen Sicherheitsprobleme zu behandeln. Es liegt in der Verantwortung des Anwenders dieses Dokuments, vor dessen Anwendung geeignete Maßnahmen für die Sicherheit und den Gesundheitsschutz des Personals zu ergreifen und dafür Sorge zu tragen, dass behördliche und gesetzliche Anforderungen eingehalten werden.
Bitumes et liants bitumineux - Détermination de la température d'équi-module de rigidité et de l’angle de phase à l'aide d'un rhéomètre à cisaillement dynamique (DSR) - Essai BTSV
Le présent document spécifie le test rapide pour caractériser un liant (dont l’acronyme BTSV provient du titre allemand : Bitumen-Typisierungs-Schnell-Verfahren). Cette méthode d’essai est réalisée à l’aide d’un rhéomètre à cisaillement dynamique (DSR). Elle est utilisée pour caractériser, de manière rapide, les bitumes et liants bitumineux et pour évaluer leur comportement à la déformation aux températures de service élevées.
Ce document traite de la réalisation d’essais sur les bitumes routiers et les bitumes modifiés neufs (non vieillis), les bitumes routiers et les bitumes modifiés ayant été soumis en laboratoire à une procédure de vieillissement (par exemple EN 12607-1 ou EN 14769) ainsi que sur les liants récupérés à partir d’enrobés. Cette méthode d’essai ne s’applique pas aux liants bitumineux contenant des particules de plus de 250 μm (par exemple du filler ou du caoutchouc broyé).
NOTE Il n’y a pas encore de recul sur l’application de cette méthode d’essai aux liants bitumineux récupérés d’émulsions bitumineuses.
Cette méthode d’essai détermine la température et l’angle de phase associé auxquels un liant bitumineux présente une valeur de module complexe en cisaillement donnée, mesurée lors d’un balayage en température croissant, à contrainte et fréquence imposées.

1 Scope
This document specifies the Binder Fast Characterization Test (for short: BTSV test, German: Bitumen-
Typisierungs-Schnell-Verfahren). The test is conducted using a Dynamic Shear Rheometer (DSR). It is used
to characterize bitumen and bituminous binders and to assess the deformation behaviour at high service
temperatures.
The test procedure described in this document covers the testing of paving grade bitumen or modified
bitumen, as fresh (unused) binders, as well as binders after laboratory ageing conditioning (e.g.
EN 12607-1, EN 14769), and also binders that have been recovered from asphalt mixtures. The test
procedure in accordance with this document is not applicable for bituminous binders with particles
larger than 250 μm (e.g. filler material, granulated rubber).
NOTE The test procedure has not been applied on bituminous binders recovered from bitumen emulsions yet.
The test determines the temperature and the associated phase angle at which a bituminous binder
exhibits a defined complex shear modulus in stress-controlled oscillation mode at constant frequency
and with continuous increase of the test temperature.

3.1
complex shear modulus
|G*|
ratio of the amplitude of the shear stress to the amplitude of the shear strain in harmonic sinusoidal
oscillation
Note 1 to entry: The (mathematical) real part of the complex shear modulus |G*| is G´. It is associated with the
elastic part of material behaviour which represents energy stored during a shear cycle. The real part is the complex
shear modulus multiplied with cosine of phase angle expressed in degrees.
Note 2 to entry: The (mathematical) imaginary part of the complex shear modulus |G*| is G´´. It is associated with
the viscous part of material behaviour which represents energy dissipated during a shear cycle. The imaginary part
is the complex shear modulus multiplied with sine of phase angle expressed in degrees.
3.2
phase angle
δ
phase difference in degrees between stress and strain in harmonic oscillation

Note 1 to entry: The shear strain is given as a percentage.
3.4
range of linear viscoelastic behaviour
range in which the complex shear modulus is independent of the shear stress or shear strain
Note 1 to entry: The procedure of BTSV testing is such that the linear viscoelastic range does not need to be
determined prior to testing.

4 Principle
This standard test procedure is used to determine the temperature T at which a bituminous binder
(BTSV)
exhibits a complex shear modulus of 15 kPa under defined stress-controlled oscillation loading in a state
of non-stationary temperature, and to determine the associated phase angle δ , without linear
(BTSV)
viscoelastic domain experimental validation.
The test shall be carried out in stress-controlled oscillation mode at a steadily increasing test
temperature.
NOTE Testing can also be done using strain-controlled mode; however, this is not within the scope of the BTSV
method as standardized.
A parallel-plate system with a plate diameter of 25 mm and a plate gap of 1 mm is used.
The test specimen is continuously subjected to oscillating loading with a frequency of 1,59 Hz. During this
loading, the test temperature is steadily increased at a constant rate within a temperature range of 20 °C
to 90 °C. The temperature range up to 30 °C serves to establish the temperature rate and is not taken into
account in the evaluation.
5 Apparatus
5.1 General
Usual laboratory and glass apparatus, together with the following:
5.2 Dynamic Shear Rheometer (DSR), as described in EN 14770, with either an integral temperature
control system or temperature control attachments, capable of controlling the temperature over a
minimum range of 20 °C to 90 °C with an accuracy of ± 0,1 °C throughout the test period. The rheometer
shall be fitted with parallel plates with a diameter of 25,00 mm ± 0,05 mm, with a constant gap across the
area of the plates. The temperature control system shall encompass both plates to avoid temperature
gradients across the plates. When the test specimen is immersed in liquid other than water, ensure that
the liquid does not affect the properties of the material being analysed. The rheometer shall operate in
stress-controlled mode and be able to record data at intervals of 2,5 s.
NOTE 1 When liquid is used to immerse the test specimen, a water/glycol mixture has been found to be suitable.
The proportions used depend on how low the temperature intended for testing is. Rheometers using radio
frequency (RF) heating and/or liquid gas cooling or other heating/cooling systems can be used in accordance with
the manufacturer's instructions.
Where the bottom plate nominally has the same diameter as the top plate, a visual check should be made
to ensure the two plates are vertically aligned. If there is any doubt as to the alignment of the top and
bottom plates, the manufacturer, or a qualified technician, should re-align the plate geometry.
NOTE 2 Apparatus with systems where the upper and lower plates have the same diameters make it easier to
remove excess material from the inserted sample.
NOTE 3 For some binders, e.g. recovered from reclaimed asphalt, the temperature range can be adjusted, allowing
higher testing temperatures. In these cases, the start temperature can be increased.
5.3 Moulds or sheet materials, for the preparation of the test specimens. The moulds or sheet
material, where used, shall be of silicone or similar material, which does not adhere to the test specimen.
For a testing geometry with a diameter of 25 mm and a gap setting of 1 mm as for this standardized
procedure, a mould with a cavity of approximately 18 mm in diameter and 2 mm deep may be used. In
any case, the operator shall ensure adequate filling of the gap according to 8.2.

The use of grease or other anti-stick products should be avoided because they can affect the adherence
