THE USE OF SPECTRAL ESTIMATES FOR PAVEMENT CHARACTERIZATION
An investigation of the uses of road profile spectral estimates for characterizing pavements has been made and is reported herein. This investigation included the development of a serviceability index prediction model based entirely on the road profile wavelength amplitude estimates. This model has been used extensively in both research and field operations and is also currently being used as the SI model standard for Mays Road Meter calibration procedures. Other pavement characterization techniques are also discussed, including the use of digital filtering techniques for obtaining more comprehensive wavelength-amplitude descriptors.
