    Abstract

    A closed form probabilistic formulation is presented for the determination of the fatigue deterioration of flexible pavements. This formulation is based on the simple phenomenological models which use Miner's law. The expected value and variances of the measure of damage are related to the statistical characteristics of the loading patterns and materials properties. A spatial coefficient of correlation is determined for the measure of damage and is used to determine the typical size of the cracked areas. This study emphasizes the need for obtaining more complete material characterization procedures which do include measurements for spatial variabilities.
