Comparison of bitumen multiple-stress creep recovery test values from the viewpoint of different test parameters

Popis výsledku v původním jazyce

Multiple Stress Creep and Recovery (MSCR) test is a suitable test for assessing the resistance of bituminous binders to permanent deformation. This is one of the most frequently used tests on Dynamic Shear Rheometer (DSR) in the world because it describes in a suitable way the nonlinear viscoelastic behavior of the bituminous binder. The test is performed at higher temperatures and is particularly suitable for modified bituminous binders. The method is described in the European standard EN 16659, which is valid in the Czech Republic since October 2016. The principle of the test is based on multiple loading and recovering of a bitumen sample, which determines the percentage of elastic recovery and non-recoverable creep compliance Jnr of the bituminous binder. The paper deals with the assessment of the influence of the different input parameters set on the DSR device - three selected stress levels, two test temperatures and a different geometry of the measuring device. The paper also compares different number of loading cycles applied during the test. Conclusions are made with respect to selecting appropriate test temperature and to consider most suitable test geometry. In case of additional stress level further laboratory assessments are needed.
