    Abstract

    The objective of this study was to evaluate the material properties of a conventional (control) and fiber-reinforced asphalt mixtures using advanced material characterization tests. The laboratory experimental program included triaxial shear strength, dynamic (complex) modulus, repeated load permanent deformation, fatigue, crack propagation, and indirect tensile strength tests. The data was used to compare the performance of the fiber-modified mixture to the control. The results showed that the fibers improved the mixture’s performance in several unique ways against the anticipated major pavement distresses: Permanent deformation, fatigue cracking, and thermal cracking.
