FATIGUE AND REPEATED-LOAD ELASTIC CHARACTERISTICS OF INSERVICE PORTLAND CEMENT CONCRETE

This report summarizes the results of an investigation of the resilient elastic and fatigue behavior of inservice concrete from pavements in Texas. Static indirect tensile tests were conducted in order to estimate the average tensile strength of each of the four projects tested. Repeated-load indirect tensile tests were conducted to determine the fatigue and resilient characteristics and the relationship between fatigue life and stress/strength ratio. Deformation measurements were taken during fatigue testing in order to determine the resilient elastic properties of the material and the changes in these properties during the test period. In addition, estimates of the variation in fatigue life and elastic properties were made.
