FATIGUE BEHAVIOR OF CEMENT-TREATED MATERIALS

Fatigue-failure criteria based on the Griffith failure theory have been developed to describe the behavior of cement-treated pavement materials subjected to repeated multiaxial stress applications. These criteria are represented by two relationships, one for curing periods of 4 weeks and the other for curing periods of 10 weeks, that show the variation of the maximum stress level as a function of the number of stress applications required to cause failure. The stress level is defined in terms of the applied principal stresses and the initial tensile strength. For a given set of applied stress pulses, there will be a maximum value of stress level. Fatigue failure occurs when the tensile strength decreases from its intitial value to the maximum value of the stress level. The number of stress applications to cause failure can thus be expressed as a function of the stress factor and the tensile strength. This relationship is independent of the duration and frequency of the applied stress pulses. The proposed criteria agree well with fatigue data from a number of investigations, which indicates their general validity.
