Asphalt concrete subjected to long-time loading at low temperatures – Deviations from the time-temperature superposition principle

The article presents the observed deviations from the time-temperature superposition principle of asphalt concretes, tested in the bending beam creep test at low temperatures for a long time of loading. In almost all tested asphalt concretes, deviations appeared after 500 s of loading at the temperature of −10 °C. Some types of bitumen presented deviations at other temperatures – usually the harder the grade of the bitumen, the higher was the...
