Evaluation of Strontium Aluminate in Traffic Paint Pavement Markings for Rural and Unilluminated Roads

Abstract

The researchers introduced different quantities of strontium aluminate to traffic paint to achieve phosphorescence. Factors to consider for this study are charging time, lux received, luminance emitted, amount of SrAl2O4:Eu added and its effects through abrasion. It was found out that the luminance emitted vs time follows a power f(x)=axⁿ where x is in minutes. There are positive trends when relating lux emitted with charging time with percent strontium aluminate added with millimeters of paint removed.
