Abstract
Para evaluar la durabilidad de los materiales de demarcación vial, existen ensayos que van desde pruebas de campo a equipos de gran escala que demandan un tiempo importante de ensayo para obtener el resultado. Por otra parte, para evaluar la resistencia a la abrasión, se utilizan métodos generales para todo tipo de pinturas. En base a lo mencionado, se implementa el equipo de Pulimento Acelerado de Áridos y el ensayo de Abrasión por vía húmeda utilizado para lechadas asfálticas con el fin de analizar el desempeño de los materiales de demarcación vial en servicio. Para ello, se hace uso de pinturas acrílicas de base acuosa y base solvente, y se comparan los valores obtenidos con el ensayo Taber Abraser en las mismas condiciones de curado. Como resultado, el ensayo de pulimento acelerado permite tener una estimación del comportamiento en servicio, con la ventaja de poder ensayar varias muestras simultáneamente bajo las mismas condiciones.
To evaluate the durability of road marking materials, there are tests ranging from field tests to large-scale equipment that require large testing time to obtain the results. On the other hand, to evaluate abrasion resistance, there are used general methods for all types of paints. For this reason, the Aggregates Accelerated Polishing Machine and the Wet Abrasion Test (used for asphalt slurries), are implemented in order to evaluate the performance of road marking materials, in service. Both waterborne and solventborne acrylic paints are used and the results are compared with the Taber Abraser Test under the same curing conditions. As a conclusion, the Accelerated Polishing Test allows to estimate in service behavior of road marking paints with the advantage of being able to test several samples under the same conditions simultaneously.
