Adaptación del ensayo de abrasión por vía húmeda para la evaluación de marcas viales: análisis de retrorreflexión y resistencia al deslizamiento
Main Article Content
Abstract
Currently, the road industry demands effective methods to evaluate the performance of road markings under service conditions. This study proposes an evaluation of road markings’ performance under wet abrasion conditions by adapting a simple test used for asphalt slurries, allowing the simulation of the combined effects of traffic and water on road markings. The methodology involves the application of paint (aqueous and solvent-based) with embedded microspheres on galvanized sheets. The samples are subjected to water abrasion cycles, and the evolution of properties such as retroreflection, slip resistance and visual appearance are evaluated. The results indicate that this procedure allows a rapid evaluation of the evolution of the road markings' properties, offering a viable and complementary alternative to more complex and expensive field tests. The retroreflection and slip resistance analyses demonstrate predictable deterioration patterns, comparable to those observed in field tests. The proposed test offers a straightforward and accessible alternative for road laboratories to predict road markings' performance under real service conditions.
