Measurement of Directional Reflectance of Pavement Surfaces and Development of Computer Techniques for Calculating Luminance

Abstract

This investigation developed and used a directional reflectance goniometer to measure the directional reflectances of eleven nine-inch pavement core samples, five asphalt and six concrete. An electronic data processing program for calculating roadway luminance based on the reflectance data obtained from the samples, was developed and reported.
