- The article presents an experimental method for testing beams made of AC16W mineral-asphalt mix in a static four-point bending test. Tests were performed at a fixed measuring temperature of 25°C and for different load levels. The conditions of the study that specify the variable characteristics of asphalt mixtures were specified. Attention was paid to the material specificity of the mixturesand the variability of the stiffness modulus was analyzed. Different ways of its determination with different load cycles are presented. The obtained results of the modules were compared with the results obtained in the dynamic test. The identification of the secant modulus from the dependence of the load curve between strain and stress for the first cycle was indicated.
