The purpose of this study is to determine the nature and causes of the variation of skid resistance with time. Included are seasonal variations and variations due to precipitation and other weather factors which influence skid resistance measurements. The results of this study are to be used to develop a prediction model for estimating the lowest value of skid resistance that a pavement will attain from measurements made at a time of the year when skid number is not at the minimum value. This interim report summarizes the findings of the first year of a three-year study. Presented is a tentative method for predicting minimum skid resistance that takes into account the precipitation history prior to the measurement and the number of days between the measurement and the data at which the minimum is expected. /FHWA/
