REFLECTIVE CHARACTERISTICS OF ROADWAY PAVEMENTS DURING WET WEATHER

Among the tasks of this ongoing study are to explore techniques to characterize and predict, as well as accurately and rapidly measure, the reflectance properties of pavement surfaces in wet weather conditions. Three fundamental tasks must be conducted to satisfy the goals of this study: predict actual full-scale roadway luminance patterns under dry and a variety of wet conditions using r-table data; describe, measure, and track pavement wetness; and classify reflectance characteristics by simple measurements of pavement physical properties. By and large, only preliminary data are avauilable at this time, but the hypotheses and techniques developed to address these tasks are briefly described here.
