Use of profile wave amplitude estimates for pavement serviceability measures. Paper presented at the 52nd Annual Meeting of the Highway Research Board HRB, Washington, D.C., January 1973.

Serviceability index models were developed based on slope variance of road profile data obtained with the surface dynamics profilometer. Subsequently, a serviceability index model was developed based on profile wave amplitude estimates of the road profile data. This model described and some of the results of its uses in field operation are presented.
