WebRetroreflectivity of a material is one technology used to enhance the readability and perception of information displayed in low-light and night-time conditions. The retroreflectivity of road markings provides visual guidance to assist driver’s awareness of lanes and road edges. WebReflectivity tests and pyramid height measurements were used to study the efficiency of the texturing processes. In a related study [2] it was found that 20µm of material removal was required to attain minimum surface reflectivity. Further removal of material affected pyramid dimensions, but did not improve surface reflectivity.
