Bituminous mixtures - Test methods for hot mix asphalt - Part 45: Saturation Ageing Tensile Stiffness (SATS) conditioning test
This European Standard specifies a test method to assess the durability of adhesion in base and binder course asphalt mixtures. The Saturation Ageing Tensile Stiffness (SATS) conditioning regime is used to age the specimens in the presence of water. A comparative test for assessing their performance before and after conditioning is also conducted. The applicability of this test method is limited to bituminous specimens with consistent air voids contents and hard binder, in particular, to asphalt concrete mixtures with a binder content between 3,5 % and 5,5 %, air voids contents between 6 % and 10 % and 10/20 pen hard paving grade bitumen. The test is intended to be used as a screening test for the assessment of a combination of aggregate, filler and additives with respect to the retained adhesion properties after simulated ageing in a moist atmosphere for lean/stiff base and binder course mixtures.
Asphalt - Prüfverfahren für Heißasphalt - Teil 45: Alterungsprüfung an gesättigten Asphalt-Probekörpern (SATS-Prüfung)
Diese Europäische Norm legt ein Prüfverfahren zur Bewertung der Dauerhaftigkeit des Verbunds in Asphaltmischgütern für Trag- und Binderschichten unter Anwendung des für Alterungsprüfungen an gesät-tigten Probekörpern (en: Saturation Ageing Tensile Stiffness, SATS) festgelegten Klimatisierungsregimes, bei dem die Probekörper in Anwesenheit von Wasser gealtert werden, sowie eine Vergleichsprüfung für die Bewertung der Leistung vor und nach der Klimatisierung fest. Die Anwendbarkeit dieses Prüfverfahrens ist auf bitumenhaltige Probekörper mit gleichbleibendem Hohlraumgehalt und hartem Bindemittel beschränkt, insbesondere auf Asphaltgemische mit einem Bindemittelgehalt zwischen 3,5 % und 5,5 %, einem Hohlraumgehalt zwischen 6 % und 10 % und aus Straßenbaubitumen mit einem Härtegrad von 10/20 pen. Diese Prüfung ist als Auswahlprüfung für die Bewertung einer Kombination von Gesteinskörnungen, Füller und Zusatzmitteln im Hinblick auf die nach simulierter Alterung in einer feuchten Atmosphäre verbleibenden Verbundeigenschaften von mageren/starren Mischgütern für Trag- und Binderschichten vorgesehen. ANMERKUNG Alternative Bedingungen für Gemische mit anderen Bindemitteln als 10/20 Straßenbaubitumen oder für andere Situationen, die nicht Gegenstand dieser Europäischen Norm sind, werden entwickelt.
Mélanges bitumineux - Méthodes d'essai pour mélange hydrocarboné à chaud - Partie 45: Saturation vieillissant l'essai de tension de la rigidité (SATS)
La présente Norme européenne spécifie une méthode d'essai permettant d'évaluer la durabilité de l'adhésivité dans les mélanges bitumineux pour couche de base et couche de liaison. L’essai de module en traction après un protocole de vieillissement en conditions saturées (Essai SATS : Saturation Ageing Tensile Stiffness) est utilisé pour vieillir les éprouvettes en présence d'eau. Un essai comparatif permettant d'évaluer leurs performances avant et après conditionnement est également réalisé. L'applicabilité de cette méthode d'essai est limitée aux éprouvettes bitumineuses ayant des pourcentages de vides conséquents et à base de bitume de grades durs, en particulier, les mélanges pour enrobés bitumineux ayant une teneur en liant comprise entre 3,5 et 5,5 , des pourcentages de vides compris entre 6 et 10 et les bitumes routiers de grade dur 10/20. L'essai est destiné à servir d'essai crible afin d’évaluer une combinaison de granulats, de filler et d’additifs en ce qui concerne la durabilité des propriétés d’adhésivité après un vieillissement simulé dans une atmosphère humide pour les mélanges rigides et pauvres en liant pour couche de base et couche de liaison.
NOTE Des conditions alternatives pour des mélanges avec des liants autres que des bitumes de grade dur 10/20 ou d’autres situations ne relevant pas de la présente Norme européenne sont à l’étude.
Bitumenske zmesi - Preskusne metode za vroče asfaltne zmesi - 45. del: Preskus staranja na zasičenih asfaltnih preskušancih (preskus SATS)
Ta evropski standard določa preskusno metodo za oceno trajnosti sprijemljivosti podlage in veziva v asfaltni zmesi za obrabne plasti. Režim staranja na zasičenih asfaltnih preskušancih (SATS) se uporablja za staranje primerkov v prisotnosti vode. Izvede se tudi primerjalni preskus za oceno njihove kakovosti pred staranjem in po njem. Uporabnost te preskusne metode je omejena na bitumenske preskušance s konsistentno vsebnostjo zraka in trdim vezivom, zlasti na bitumenske betone z deležem veziva med 3,5 % in 5,5 %, vsebnostjo zraka med 6 % in 10 % ter tršim cestogradbenim bitumnom (10/20). Preskus naj bi se uporabljal kot presejalni preskus za oceno kombinacije agregata, polnila in dodatkov ob upoštevanju ohranjenih lastnosti sprijemljivosti po simuliranem staranju v vlažnem okolju za revno/togo podlago in zmesi za obrabne plasti.

EN 12697-45:2012 (E) 6 1 Scope This European Standard specifies a test method to assess the durability of adhesion in base and binder course asphalt mixtures. The Saturation Ageing Tensile Stiffness (SATS) conditioning regime is used to age the specimens in the presence of water. A comparative test for assessing their performance before and after conditioning is also conducted. The applicability of this test method is limited to bituminous specimens with consistent air voids contents and hard binder, in particular, to asphalt concrete mixtures with a binder content between 3,5 % and 5,5 %, air voids contents between 6 % and 10 % and 10/20 pen hard paving grade bitumen. The test is intended to be used as a screening test for the assessment of a combination of aggregate, filler and additives with respect to the retained adhesion properties after simulated ageing in a moist atmosphere for lean/stiff base and binder course mixtures. NOTE Alternative conditions for mixtures with binders other than 10/20 hard grade bitumen or other situations not covered by this European Standard are being developed. 2 Normative references The following documents, in whole or in part, are normatively referenced in this document and are indispensable for its application.

They are then transferred into a pressurised vessel partially filled with water where they are subjected to a conditioning procedure by storage at 85 °C temperature and 2,1 MPa pressure for 65 h. The ratios of the stiffness, measured by indirect tension on cylindrical specimens, before and after conditioning by storage under increased pressure and elevated temperature on the individual specimens situated above the water are averaged to determine the sensitivity of the material to ageing and moisture. The whole process is referred to as the Saturation Ageing Tensile Stiffness (SATS) conditioning test. The average ratio is the SATS durability index of the mixture components when the comparative test is the indirect tensile stiffness modulus. NOTE Tests other than stiffness by indirect tension on cylindrical specimens can be used as the comparative test. 5 Apparatus 5.1 Sample manufacture 5.1.1 Asphalt mixer 5.1.2 Coring equipment 5.1.3 Saw for cutting asphalt 5.2 Conditioning regime 5.2.1 Vacuum desiccator and vacuum pump, including manometer or calibrated vacuum gauge in accordance with EN 12697-5. 5.2.2 Balance with a capacity greater than the mass of a sample that is accurate to 0,1 g. 5.2.3 Pressure/temperature vessel designed to operate at (2,1 ± 0,1) MPa between 80 °C and 115 °C and which shall be made from stainless steel, having internal dimensions adequate to contain the specimen tray (see 5.2.7) and an
