FATIGUE DAMAGE OF ASPHALT UNDER COMPOUND-LOADING

The results of an investigation suggest that, for the various forms of compound-loading investigated, i.e.: (1) All other variables except stress level maintained constant; (2) all other variables except temperature maintained constant; and (3) both stress and temperature level varied, fatigue life is predicted with acceptable accuracy by a linear cumulative damage rule. Test were carried out in the controlled stress mode in rotating bending fatigue machines. Because of the inherent variability of the material, the ability of a linear cumulative damage rule to predict compound-loading fatigue life is assessed over a range of probability of failure levels. The results indicate that there is reasonable probability that the cumulative cycle ratio at failure will be equal to or greater by a acceptable amount than unity.
