Serviceability index values obtained from the Mays meter and from the surface dynamics profilometer have been shown at times to differ by more than a point. A hypothesized explanation of these large discrepancies, based on the responses of the two machines to roughness with different ranges of wavelengths, is presented. Data from two sets of test sections are shown to be consistent with the hypotheses. The repeatability and day-to-day consistency of the Mays meter are also analyzed. /Author/
