“…Praticò et al studied the photoluminescence phenomenon in terms of loading and unloading according to the type of pavement (dense or gap-graded bituminous mixes), and the paint treatment by applying a coating with photoluminescent properties on the top layer of the pavement [31]. Gutiérrez and Colorado developed a photoluminescent coating made from strontium aluminate and expanded polyethylene waste for use in asphalt pavements and obtained acceptable mechanical properties [32].…”

Photoluminescent materials used on street and road pavements could absorb solar energy during the day and emit it at night, which will save energy and improve visibility with a consequent improvement in road safety. The aim of this study is to evaluate the luminance of different photoluminescent applications for pavements (bituminous mixes, mortars, and paints) in which strontium aluminate and glass beads were used. Sunlight was simulated with two bulbs, one LED and one UV bulb, inside a measuring apparatus specially developed for this work. The luminance of the different designed solutions was determined at different time periods after their excitation. The results obtained showed that luminescent paints can reach higher luminance than bituminous mixes and mortars. The colour of the base surface on which the paints are applied had a great influence on the obtained luminance, which increases with the aluminate and glass beads content. Among all the solutions evaluated, the paint made with 60% aluminate and 6% glass beads, spread on a white surface, allowed the highest luminance values to be obtained. This study leads to the conclusion that it is possible to achieve a good photoluminescent level while economising on the amount of materials necessary.
