Bituminous mixtures - Test methods for hot mix asphalt - Part 46: Low temperature cracking and properties by uniaxial tension tests
This European Standard specifies uniaxial tension tests for characterising the resistance of an asphalt mixture against low temperature cracking. The results of the uniaxial tension tests can be used to evaluate the following:
tensile strength in dependence of the temperature, using the uniaxial tension stress test (UTST);
minimum temperature that the asphalt can resist before failure, using the thermal stress restrained specimen test (TSRST);
tensile strength reserve in dependence of the temperature (using a combination of TSRST and UTST);
relaxation time, using the relaxation test (RT);
creep curve to back calculate rheological parameters, using the tensile creep tests (TCT);
fatigue resistance at low temperatures due to the combination of cryogenic and mechanical loads, using the uniaxial cyclic tension stress tests (UCTST).
Asphalt - Prüfverfahren für Heißasphalt - Teil 46: Widerstand gegen Kälterisse und Tieftemperaturverhalten bei einachsigen Zugversuchen
Diese Europäische Norm legt einachsige Zugversuche zur Bestimmung des Wider¬standes eines Asphaltgemischs gegen Kälterisse fest. Die Ergebnisse der einachsi¬gen Zugversuche können zur Beurteilung folgender Eigenschaften verwendet werden:
- Zugspannung bei einer festgelegten Temperatur unter Anwendung des direkten (einachsigen) Zugversuchs (en: Uniaxial Tension Stress Test, UTST);
- Tiefsttemperatur, bis zu der der Asphalt dem Ausfall widerstehen kann, unter Anwendung des Abkühlversuchs (en: Thermal Stress Retained Specimen Test, TSRST);
- Zugfestigkeitsreserve bei einer festgelegten Temperatur (unter Anwendung einer Kombination aus TSRST und UTST);
- Relaxationszeit unter Anwendung des Relaxationsversuchs (en: Relaxation Test, RT);
- Kriechkurve, um durch Zugkriechversuche (en: Tensile Creep Test, TCT) auf rheologische Parameter zurückrechnen zu können; und
- Ermüdungsverhalten bei niedrigen Temperaturen aufgrund der Kombination kryogener und mechanischer Beanspruchungen unter Anwendung von einachsigen zyklischen Zugversuchen (en: Uniaxial Cycling Tension Stress Test, UCTST).
