description | Investigating the behavior of asphalt concrete at low loading frequency is essential to understand the thermal fatigue damage due to cyclic day-night temperature cycles, where the loading frequency is usually very low. This study determines some properties (e.g., fatigue damage, dissipated energy, and stiffness) of asphalt concrete beam samples at a low frequency of loading using four-point bending test apparatus. Results show that fatigue damage is more significant at a lower frequency of cyclic loading and the number of cycles at failure becomes stable at a frequency equal to or lower than 0.01 Hz. The concept of initial stiffness at the 50th cycle of loading is inappropriate at a low frequency of loading as the stiffness reduction with a number of loadings is so considerable at a frequency of loading. In addition, the dissipated energy per loading cycle decreases with a decrease in loading frequency. |
