ABSTRACT
This study aimed to investigate some engineering properties of a typical asphalt concrete reinforced by different percentages of nylon fibers. 12 mm long nylon6/6 fibers have been added to a typical asphalt concrete at different percentages of 0.1, 0.2 and 0.3% (by the weight of total mixture), and the volumetric properties, indirect tensile strength, Marshall stability and permanent deformation behavior of the mixtures have been investigated. The permanent deformation behavior of the mixtures has been studied by conducting dynamic creep tests at different stress levels of 200 and 400 kPa, and different temperatures of 40, 50 and 60°C on the mixtures. The results show that the mixture reinforced by 0.1% of nylon fibers has a higher Marshall stability, Marshall quotient, indirect ensile strength and resistance against permanent deformation than the control mixture and the mixtures containing 0.2 and 0.3% of nylon fibers.
