Bituminous mixtures - Test methods - Part 12: Determination of the water sensitivity of bituminous specimens
This European Standard specifies three test methods for determining the effect of saturation and accelerated water conditioning:
- 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 for a bituminous mixture 1 h after mixing, where the bonding of bitumen and aggregate can be equated to a bonding value.
Method C is suitable for soft asphalt with bitumen of kinematic viscosity at 60 °C of 4 000 mm2/s or less.
These methods can be used to evaluate the effect of water on asphalt mixtures with or without anti-stripping additives including liquids, such as amines; and fillers, such as hydrated lime or cement.
Asphalt - Prüfverfahren - Teil 12: Bestimmung der Wasserempfindlichkeit von Asphalt-Probekörpern
Diese Europäische Norm legt drei Prüfverfahren zur Bestimmung des Einflusses der Wassersättigung und der beschleunigten Klimatisierung durch Wasserlagerung fest:
- Verfahren A dient zur Prüfung der indirekten Zugfestigkeit von zylindrischen Asphalt-Probekörpern;
- Verfahren B dient zur Prüfung der Druckfestigkeit von zylindrischen Asphalt-Probekörpern;
- Verfahren C dient zur Bestimmung des Haftvermögens eines Asphaltmischgutes 1 h nach dem Mischen, wobei das Haften von Bitumen auf der Gesteinskörnung als Haftwert bezeichnet wird.
Verfahren C eignet sich für Softasphalt mit Bitumen einer kinematischen Viskosität von höchstens 4 000 mm2/s bei 60 °C.
Diese Verfahren können zur Bewertung des Effekts dienen, den Wasser auf Asphaltmischungen mit oder ohne haftungsverbessernde(n) Zusätze(n), einschließlich Flüssigkeiten, wie z. B. Aminen, und Füllstoffe(n), wie z. B. Kalkhydrat oder Zement, hat.
Mélanges bitumineux - Méthodes d’essai - Partie 12 : Détermination de la sensibilité à l'eau des éprouvettes bitumineuses
La présente Norme européenne spécifie trois méthodes d'essai pour déterminer l'effet d'une saturation et d'une conservation accélérée dans l'eau.
- 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 la valeur d'adhésivité des mélanges bitumineux 1 h après mélange,
lorsque l'adhésivité du bitume et du granulat peut être assimilée à une valeur d‘adhésivité.
La méthode C est applicable aux mélanges bitumineux souples avec un bitume ayant une viscosité cinématique à 60 °C inférieure ou égale à 4 000 mm2/s.
Ces modes opératoires peuvent servir à l'évaluation de l'effet de l'eau sur les enrobés 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.
Bitumenske zmesi - Preskusne metode - 12. del: Ugotavljanje občutljivosti bitumenskih preskušancev za vodo
Ta evropski standard opisuje tri preskusne metode za ugotavljanje vpliva nasičenosti in pospešenega vodnega pogojevanja.
Metode je mogoče uporabiti za vrednotenje vpliva vlage z aditivi proti luščenju ali brez njih, vključno s tekočinami, kot so amini, in polnili, kot je hidratizirano apno ali cement:
- metoda A uporablja indirektno natezno trdnost valjastih preskušancev bitumenskih zmesi;
- metoda B uporablja tlačno trdnost valjastih preskušancev bitumenskih zmesi;
- metoda C definira vrednost vezave mehkih asfaltnih zmesi 1 h po mešanju, pri čemer je vezava bitumna in agregata enakovredna vrednosti vezave.
Metodi A in B v povprečju dajeta iste rezultate. Vendar pa metoda B ni primerna, če je koeficient vitkosti manjši od 0,5.
Metoda C je primerna za mehke asfaltne zmesi z bitumnom z viskoznostjo 4000 mm2/s pri 60 °C, za katero metodi A in B nista primerni.
OPOMBA: Metodi A in B sta primerni za mehke asfaltne zmesi z bitumnom z viskoznostjo pri 60 °C, večjo od 4000 mm2/s.
