ABSTRACT
This article attempts to explain photometry system capable of measuring the photometric characteristics (coefficient of luminous intensity and coefficient of retroreflection) in the range of geometries defined in the rules of retroreflective materials used on road equipment. This system allows to characterize the retroreflective materials consisting of glass beads and microprismatic.

KEYWORDS
