ESTIMATION OF ASPHALT CONCRETE FATIGUE CURVES – A DAMAGE THEORY APPROACH. Castro, M., Sánchez, J. A. Construction and Building Materials, 22 (6), 1232-1238, 2008
Abstract
In order to represent the behaviour during fatigue tests of asphalt concrete mixtures, a phenomenological model, based on the continuous damage theory, has been developed. From this model, a method for estimation of fatigue curves was formulated. From a practical point of view, the use of this method enables classic fatigue curves to be estimated with a smaller number of specimens tested. This method of estimating fatigue curves was applied to three mixtures, and its results were compared with those of the standard procedure.
