Improving drivers visibility in night time conditions is vital. Night-time visibilityrepresents one of the most important features of road safety. Within such context, theuse of photoluminescent road markings could represent an enhancement with regard to roadsafety. Consequently, the objective of the investigation here described was confined into theanalysis of photoluminescent paints by referring to dense-graded and open-graded frictioncourses. Measurements, based on photometry technique, were carried out in the laboratory.Cores extracted from the surface layer of known pavements were used. Transitory effects(charge and discharge) and decay phenomena were investigated and modelled as a functionof treatment and pavement characteristics (paint quantity, hot mix asphalt volumetrics, etc.).The results highlight that the photoluminescent performance depends on the volumetriccharacteristics of bituminous mixtures. Results can benefit both researchers and practitionersand can allow optimising painting treatments for different bituminous mixtures.
