Bituminous mixtures - Test methods for hot mix asphalt - Part 12: Determination of the water sensitivity of bituminous specimens
This European Standard describes three test methods for determining the effect of saturation and accelerated water conditioning.
These methods can be used to evaluate the effect of moisture with or without anti-stripping additives including liquids, such as amines, and fillers, such as hydrated lime or cement:
method A uses the indirect tensile strength of cylindrical specimens of bituminous mixtures;
method B uses the compression strength of cylindrical specimens of bituminous mixtures;
method C defines the bonding value of soft asphalt mixtures 1 h after mixing, where the bonding of bitumen and aggregate can be equated to a bonding value.
Method A and method B give the same result in average. However, if the slenderness of the specimens is less than 0,5, method B is not suitable.
Method C is suitable for soft asphalt mixtures with bitumen of viscosity at 60 ºC of 4000 mm2/s or less, for which methods A and B are not suitable.
NOTE Methods A and B are suitable for soft asphalt mixtures with bitumen of viscosity at 60 ºC greater than 4000 mm2/s.
Asphalt - Prüfverfahren für Heißasphalt - Teil 12: Bestimmung der Wasserempfindlichkeit von Asphalt-Probekörpern
Diese Europäische Norm beschreibt drei Prüfverfahren zur Bestimmung des Einflusses der Wassersättigung und der beschleunigten Klimatisierung durch Wasserlagerung.
Diese Verfahren können zur Beurteilung der Auswirkung von Feuchte mit oder ohne Haftvermittler, einschlie߬lich Flüssigkeiten, wie z. B. Aminen, und Zusätze, wie z. B. hydratisierter Kalk oder Zement, herangezogen werden:
Verfahren A: Es wird die indirekte Zugfestigkeit von zylindrischen Asphalt-Probekörpern geprüft;
Verfahren B: Es wird die Druckfestigkeit von zylindrischen Asphalt-Probekörpern geprüft;
Verfahren C: Es wird das Haftvermögen von Softasphaltmischungen 1 h nach dem Mischen defi¬niert. Das Haften von Asphalt auf der Gesteinskörnung wird als „Haftwert“ bezeichnet.
Verfahren A und B ergeben den gleichen Durchschnittswert. Verfahren B ist jedoch nicht geeignet, wenn die Schlankheit der Probekörper geringer als 0,5 beträgt.
Das Verfahren C eignet sich für Softasphaltmischungen mit Asphalt mit einer Viskosität von maximal 4 000 mm2/s bei 60 °C. Im diesen Fall sind die Verfahren A und B ungeeignet.
ANMERKUNG Die Verfahren A und B eignen sich für Softasphaltmischungen mit Asphalt mit einer Viskosität höher als 4 000 mm2/s bei 60 °C.
Mélanges bitumineux - Méthodes d'essai pour mélange hydrocarboné à chaud - Partie 12 : Détermination de la sensibilité à l'eau des éprouvettes bitumineuses
La présente Norme européenne décrit trois modes opératoires pour la détermination de l'effet d'une saturation et d'une immersion accélérée dans l'eau.
Ces modes opératoires peuvent servir à l'évaluation de l'effet de l'humidité avec ou sans dopes d'adhésivité aussi bien sous forme de liquides comme les amines que de fillers comme la chaux hydratée ou le ciment.
- La méthode A utilise la résistance à la traction indirecte des éprouvettes cylindriques de mélanges bitumineux ;
- la méthode B utilise la résistance à la compression des éprouvettes cylindriques de mélanges bitumineux ;
- la méthode C définit l'adhésivité des mélanges hydrocarbonés mous 1 h après mélange, lorsque l'adhésivité du bitume et du granulat peut être assimilée à une adhésivité.
La méthode A et la méthode B donnent, en moyenne, le même résultat. En revanche, si l'élancement des éprouvettes est inférieur à 0,5, la méthode B n'est pas applicable.
La méthode C est applicable aux mélanges hydrocarbonés mous avec un bitume ayant une viscosité à 60 °C inférieure ou égale à 4 000 mm2/s, pour lesquels les méthodes A et B sont inappropriées.
NOTE Les méthodes A et B sont adaptées aux mélanges hydrocarbonés mous avec un bitume ayant une viscosité à 60 ºC supérieure à 4 000 mm2/s.

3.3 water sensitivity (in accordance with method B) the i/C value obtained on compacted specimens of wet (water conditioned) specimens to that of dry specimens of a bituminous mixture 3.4 indirect tensile strength ratio (ITSR) ratio of the indirect tensile strength of wet (water conditioned) specimens to that of dry specimens, expressed in percent 3.5 indirect tensile strength (IST)
maximum tensile stress applied to a cylindrical specimen loaded at the specified test temperature and speed of displacement of the compression testing machine, determined in accordance with EN 12697-23 3.6 compressive strength ratio (i/C)

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. SIST EN 12697-12:2009

One subset is maintained dry at room temperature while the other subset is saturated and stored in water at elevated conditioning temperature. After conditioning, the indirect tensile strength of each of the two subsets is determined in accordance with EN 12697-23 at the specified test temperature.
