EVS-EN 12697-46:2012

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 tensile strength in dependence of the temperature by uniaxial tension stress test (UTST); - the minimum temperature that the asphalt can resist before failure by thermal stress restrained specimen test (TSRST); - the tensile strength reserve in dependence of the temperature (by a combination of TSRST and UTST); - the relaxation time by the relaxation test (RT); - the creep curve to back calculate rheological parameters by tensile creep tests (TCT); - the fatigue resistance at low temperatures due to the combination of cryogenic and mechanical loads by uniaxial cyclic tension stress tests (UCTST).
