Methods which enhance random vibration test development practices by demonstrating an application for fatigue calculations on random vibration data from an entire road durability test are presented. Background is provided on existing techniques for estimating fatigue damage in the frequency domain using power spectral densities of stress. In addition, a general model for stress response to random acceleration inputs is offered to allow using acceleration time history data in fatigue calculations. Finally, a method is presented for processing a complete road durability test's acceleration time history data to stationary segments suitable for frequency domain test development. Recommendations are also included to allow for test time compression from editing as well as exaggeration methods.
