WebRetroreflection occurs when a surface returns a large portion of directed light beam back to its source. Retroreflective materials appear brightest to observers nearest the light source (such as a motorist). The object’s brightness depends on the intensity of the light striking the object and the materials the object is made of. WebRetro-reflectivity testing methods are a means for measuring the amount of light that is reflected back. Retro-reflectivity testing allows a DOT to determine that the markings …

WebReflectivity test equipment cannot pick up “heat” which is the main discussion point. It picks up certain nanowaves of the light spectrum with “shiny” or gloss getting a lot of air play – which has nothing to do with heat. So, given the above, reflectivity does not show how heat is managed, only light reflected.
