Abstract:The purpose of this project was to research and evaluate the different variations (temperature, notch dimensions, load rates, etc.) of the Semi-Circular Bend (SCB) Flexibility Index (FI) test. This project was also aimed to develop a method of comparison of the fatigue performance results between the SCB FI and the Overlay Tester to help provide the industry with an alternate means of fatigue cracking evaluation that correlates to the NJDOT’s Overlay Tester procedure.
