Abstract
The main purpose of this paper is to evaluate the possibility of improvement in fatigue resistance of asphalt concrete mixture using the industrial waste material of K fiber. In this research, as an experimental equipment, the MTS with Closed-Loop Servohydraulic System was used and it was designed according to the U.S. standard testing procedure of ASTM D 4123. According to the test results, the optimum content of fiber with the length of 8mm was about 0.2 percent of total mixture weight. The optimum asphalt content for the fiber-reinforced asphalt concrete was about 5.5 percent of total mixture weight. Fatigue resistance of fiber-reinforced asphalt concrete was noticeable compared to the conventional dense-graded 20 asphalt concrete. In addition, the resilient moduli of fiber-reinforced asphalt mixture were $1.15{\sim}1.18$ times higher than those of conventional asphalt concrete.
