Bituminous mixtures - Test methods for hot mix asphalt - Part 39: Binder content by ignition
This document describes a test method for the determination of the binder content of samples of bituminous mixtures by ignition. As such, it is an alternative to the more traditional method of extracting the binder using solvents. The method can be used for evaluation of mixture composition because the remaining aggregate can be used for determining aggregate gradation and density, provided excessive breakdown of the aggregate particles does not occur at the temperature reached. The results can be used for process control or checks on the compliance of mixtures. However, the need for calibration of a mixture, either on the complete mixture or on each of its component materials separately, before an analysis can be carried out makes this method easier to use with regularly used mixtures rather than with an extensive range of different mixtures from different aggregate sources. The test method is equally suitable for the analysis of mixtures containing unmodified or modified binders because the method has to be calibrated for each mixture being checked when calibration on mixtures is used. In case of doubt/dispute, the determination of the calibration value based on laboratory-prepared bituminous mixtures (see A.1 and A.2) is the reference method.
Asphalt - Prüfverfahren für Heißasphalt - Teil 39: Bindemittelgehalt durch Thermoanalyse
Dieses Dokument beschreibt ein Prüfverfahren zur Bestimmung des Bindemittelgehaltes von Asphalt-Proben durch Thermoanalyse. Als solches stellt es eine Alternative zum eher traditionellen Verfahren der Bindemittelextraktion mit Lösemitteln dar. Das Verfahren kann zur Bewertung der Mischgutzusammensetzung verwendet werden, weil die verbleibenden Gesteinskörnungen zur Bestimmung der Korngrößenverteilung der Gesteinskörnungen und der Dichte verwendet werden können, vorausgesetzt, dass bei der erreichten Temperatur kein übermäßiger Zerfall der Gesteinskörnungen auftritt. Die Ergebnisse können zur Prozesssteuerung oder zur Überprüfung der Übereinstimmung von Mischgütern mit Anforderungen verwendet werden. Durch die Notwendigkeit, das Mischgut als Ganzes oder seine Bestandteile einzeln zu kalibrieren, bevor eine Analyse durchgeführt werden kann, eignet sich dieses Verfahren eher für die Anwendung auf regelmäßig verwendete Mischgüter als auf eine ganze Reihe verschiedener Mischgüter mit Gesteinskörnungen unterschiedlicher Herkunft. Das Prüfverfahren ist ebenso geeignet für die Analyse von Mischgütern mit nicht modifizierten oder modifizierten Bindemitteln, weil es für jedes zu überprüfende Mischgut zu kalibrieren ist, sofern eine Kalibrierung an Mischgütern durchgeführt wird. In Zweifels- oder Streitfällen gilt die Bestimmung des
Kalibrierwertes auf der Grundlage von im Labor hergestellten Asphalt-Mischgütern (siehe A.1 und A.2) als
Referenzverfahren.
Mélanges bitumineux - Méthodes d'essai pour mélange hydrocarboné à chaud - Partie 39: Détermination de la teneur en liant par calcination
Le présent document décrit les procédures à suivre pour la détermination de la teneur en liant d’échantillons
de mélanges bitumineux par calcination. Comme telle, il représente une alternative à la méthode plus
traditionnelle d’extraction de liant au moyen de solvants. La méthode peut être utilisée pour l’évaluation de la
composition d’un mélange, les granulats résultants pouvant servir à déterminer la granularité et la masse
volumique du granulat à condition que les grains n’aient pas subi d’éclatements excessifs à cause de la
température atteinte. Les résultats peuvent être utilisés pour la maîtrise de la fabrication ou pour des
vérifications de conformité des mélanges. Toutefois, la nécessité de calibrer un mélange, soit sur le mélange
complet, soit séparément sur chacun de ses matériaux constitutifs, avant de réaliser une analyse rend cette
méthode préférable pour des mélanges utilisés régulièrement, plutôt que pour des familles de mélanges
comportant des composants d’origines variées. La méthode d’essai est applicable également pour des
mélanges comportant des liants modifiés ou non, le calibrage étant effectué pour chaque mélange à analyser.
En cas de doute ou de litige, la détermination du facteur de calibrage fondé sur des mélanges bitumineux
préparés en laboratoire (voir A.1 et A.2) est la procédure de référence.
Bitumenske zmesi - Preskusne metode za vroče asfaltne zmesi - 39. del: Ugotavljanje deleža veziva z vžigom
Ta dokument opisuje preskusno metodo za ugotavljanje deleža veziva v vzorcih bitumenskih zmesi z vžigom. Ta metoda se lahko uporablja namesto tradicionalnejše metode ekstrakcije veziva s topili. Metodo je mogoče uporabiti za vrednotenje sestave zmesi, ker je preostali agregat mogoče uporabiti za določanje gradacije in gostote agregata, če pri doseženi temperaturi ne pride do presežnega razpadanja delcev agregata. Rezultate je mogoče uporabiti za kontrolo procesa ali preverjanje skladnosti zmesi. Vendar je ta metoda zaradi potrebe po umerjanju zmesi, in sicer končne zmesi ali ločenih kompozitnih materialov, pred analizo enostavnejša za uporabo pri redno uporabljenih zmeseh kot pri širšem sklopu različnih zmesi različnih agregatnih virov. Preskusna metoda je prav tako ustrezna za analizo zmesi, ki vsebujejo nemodificirana ali modificirana veziva, ker jo je treba umeriti za vsako zmes, ki se preverja, kadar se umerjanje uporablja pri zmeseh. V primeru dvoma ali spora je referenčna metoda določanje vrednosti za umerjanje na osnovi laboratorijsko pripravljenih bitumenskih zmesi (glejte A.1 in A.2).

3 to entry: Methods for determining the calibration values are given in Annex A (normative). 3.4 target temperature temperature to which the furnace would raise the sample in the test without the rise in temperature due to the exothermic reaction of burning the binder Note 1 to entry: The target temperature (usually 540 °C) is determined during the calibration. 3.5 test completion time time from when the temperature in the furnace returns to the target temperature, after the initial rise above that temperature, to when the test is completed with the sample having nominally reached constant mass Note 1 to entry: If a furnace with an internal balance is used, the completion time is when the loss of mass between individual readings taken at 1 min intervals for three consecutive minutes is less than a constant mass limit. If a furnace without an internal balance is used, the completion time is when the change in the mass of the sample after further ignition for 15 min is less than a constant mass limit. 4 Principle The test method determines the binder content of bituminous mixtures by ignition of the mixture in a furnace. The corrected binder content is obtained by a calculation that includes a calibration term. Calibration terms are determined for particular asphalt mixtures or aggregates. Two test methods are described: Method A utilises a furnace with an internal balance; Method B permits the use of a furnace and external balance. Re-determination (re-calibration or re-calculation depending on the calibration method chosen from Annex A) shall be undertaken for each significant change in the mixture, including changes in the constituent materials or their proportions. NOTE 1 The ignition process should have a controlled rise in temperature in order to avoid excessive heating of the mineral aggregate which can break down the aggregate particles depending on the petrographic composition. NOTE 2 The calculation of the calibration value based on parallel analysis with extraction methods (A.1 and A.3) is appropriate for mixtures for which the intended proportions of the constituent materials are not known. 5 Apparatus 5.1 Furnace. 5.1.1 Furnace, capable of burning all the binder with the features detailed in 5.1.2 to 5.1.6 for Method A and 5.1.2 to 5.1.4 for Method B. NOTE 1 The temperature required to burn all the binder will depend on the technology used and is determined as part of the calibration procedure (see Annex A). NOTE 2 The furnace should not have to operate at its maximum capacity in order to allow flexibility and to ensure long service. 5.1.2 Sample chamber, having an internal capacity capable of taking the sample without touching the sides and with the maximum dimensions not greater than twice the minimum dimensions. NOTE Larger chamber sizes may expedite testing by allowing larger sample basket(s) (and thus the material to be tested can be placed in thinner layers). 5.1.3 Automatic lock, that shall not allow the door to be opened until the completion of the test procedure, and a warning system to indicate the end of the pre-programmed temperature cycle. SIST EN 12697-39:2012
The furnace shall have a fan with the capability to pull sufficient air through the furnace to expedite the test and to reduce the escape of smoke into the laboratory. NOTE 1 The method for reducing furnace emissions can comprise a filter and a post combustion chamber that is designed to eliminate the toxic residues produced by burning the binder. NOTE 2 If mechanical ventilation is used, the air flow should be adjusted so as not to affect the operation of the equipment (e.g. a forced air extraction system may result in a loss of fines and the generation of fumes from the furnace). 5.1.5 Internal balance, capable of detecting mass variations of ± 0,1 g in the sample within the baskets.
The balance shall be thermally isolated from the furnace chamber. 5.1.6 Data collection system and a warning system, which shall be capable of being set to a value such that the loss in mass between individual readings taken at 1 min intervals for three consecutive minutes at end of the pre-programmed temperature cycle is not higher than the values stated in Table 1. 5.2 Metal baskets, manufactured from perforated sheet of tempered stainless steel or other suitable material that permits adequate air flow through the sample and retains the majority of the sample throughout the test.
The dimensions shall be specified by the furnace manufacturer to provide the maximum surface area for the sample while still providing sufficient room to safely load and unload the sample. The baskets shall be capable of being nested. 5.3 Catch pan, made of stainless steel with dimensions sized to accommodate the metal baskets specified in 5.2. 5.4 Oven, with convection or forced draft, capable of maintaining a temperature of (110 ± 5) °C in the vicinity of the samples. 5.5 External balance, capable of weighing the mass of trays plus the catch pan and the test sample according to Table 1 to ± 0,1 g. 5.6 Safety equipment, including safety glasses or face shield, high temperature gloves, and long sleeved jacket. 5.7 Heat-resistant surface, capable of withstanding 650 °C and able to act as a heat sink that can speed the cooling of the sample baskets, and protective cage, capable of completely surrounding the sample baskets and preventing accidental physical contact with them. NOTE An appropriate sign warning of the danger of ‘Very Hot Surfaces’ should be attached to the protective cage. 5.8 Pan, larger than the sample basket(s), for transferri
