Fatigue Test on Cold-Recycled Cement Stabilized Base Material

Abstract:

In this paper, we present the fatigue equation through the bending fatigue test which is loaded at the three dividing point on the beam specimen and by using the two-parameter we calculate distraughtly the probability distribution of the fatigue life of cold recycling materials. we analysis the mechanism of fatigue damage by analyzing the microscopic composition of the cold recycled materials. The results show that anti-fatigue performance and fatigue life to the stress sensitive degree of cold recycled materials, while in condition of high stress ratio, the content of gravel has limited impact on fatigue performance of cold recycled materials.
