DAMAGE BASED MODEL FOR PREDICTION OF ASPHALT CONCRETE FATIGUE CURVES

DAMAGE BASED MODEL FOR PREDICTION OF ASPHALT CONCRETE FATIGUE CURVES. Castro, M., Sánchez, J. A. Journal of Materials in Civil Engineering, 19 (8), 700-702. 2007.

Abstract
In order to represent the behavior of asphalt concrete mixtures during fatigue tests, 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, this method could allow us to estimate classic fatigue curves testing a smaller number of specimens. The formulated method was applied to three mixtures, and results were compared with ones from the standard procedure for determining fatigue curves.
