Evaluation of Light Reflectiveness of Modern Pavement: Standard Tungsten Incandescent and LED

The objective of this research was to evaluate the reflectiveness of the two most commonly used modern pavement systems in the United States (concrete and asphalt). The R table used for roadway lighting design were established several decades ago as a critical parameter for determining the light reflectivity (luminance) of pavement surfaces. With the existence of modern pavement systems and also the new lighting technologies, it is necessary to...
