Increase in fatigue strength: The number of load cycles that a material can tolerate at a constant stress level reflects the fatigue strength of that material (Mallela et al., 2004). Swanson and Thompson (1967) studied the curve between the applied stress-to-static strength ratio and the number of cyclic loads to describe fatigue strength. The number of cyclic loading increases adversely to the ratio of applied stress to static strength. They downplayed the importance of fatigue in lime-treated soil because strength gained over time balanced the fatigue effect. In addition, Mallela et al. (2004) reported that the strength developed over time reduces the stress-to-strength ratio, thereby increasing fatigue strength
