Abstract
The paper presents a method of bending beam test and its importance for evaluation of asphalt mixtures behaviour at low temperatures. Two types of asphalt mixtures: asphalt concrete AC with normal paving grade bitumen and stone mastic asphalt SMA with SBS-modified bitumen were tested. Long-term oven ageing (LTOA) test was also used in the laboratory according to SHRP procedure. The Burgers model was applied and rheological parameters of asphalt mixtures were determined in range of temperature from -10ºC to 10ºC. It has been found that the theoretical Burgers model fits well the experimental data obtained from the creep test. The testing method of bending beam under constant load was relatively simple and easy to use. The paper presents the method of testing, numerical results and analysis of data.
