The primary objective of this study was to determine whether homogeneously dispersed polyester fibers improve the tensile strength and moisture susceptibility properties of asphaltic concrete. The secondary objective was to analyze the effects of changing the denier, length, and percentage of a single fiber type. The first phase of the experimental plan was to perform a Marshall method of mix design on all the fiber and nonfiber asphaltic concrete mixtures. The optimum asphalt cement contents that were determined from these tests were then used when producing the mixtures for the indirect tensile tests. The indirect tensile test was selected for the second phase of this study because it enables simultaneous analyses of tensile and moisture susceptibility properties.
