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).
