Mejoramiento de la señalización vial en ciclorrutas con el uso de la tecnología fotoluminiscente

Abstract

The purpose of the research was to find a way to improve the visibility of bicycle paths through the use of photoluminescent technology. We started with a normative review of photoluminescent technology, then selected a photoluminescent material that would be the most suitable for implementation in bike lanes depending on its affordability and visually evaluated its performance in asphalt and hydraulic concrete specimens. Twelve samples were used in total, six asphalt concrete specimens and six hydraulic concrete specimens. When reviewing the Colombian standard, there is no specification for photoluminescent materials applied in road signs and after a review in the different countries where this technology has been used, no specification was found either, since this technology is relatively new and its objective has been artistic applications in many cases. Of the available materials found in the local market, photoluminescent epoxy paint was chosen because it is intended for use on floors. The results indicate that by visual inspection the paint works best on a white surface as traditional paint for road marking and demarcation and when applied without any layer underneath it does not reflect the expected luminescence, in this case the traditional paint used for traffic demarcation and it is defined that this paint does not work mixed because it loses its luminescence. The results of luminescence time indicate that with an exposure of three hours for the recharge of the material is enough to last at least eight hours, according to the test performed in the soil laboratory of the Engineering Faculty of the Universidad La Gran Colombia.
