Resumen
Es fundamental reconocer la importancia de las carreteras en la vida diaria del ser humano y cuan necesario es, por tanto, mantenerlas en buen estado. Se sabe que las carreteras presentan un desgaste continuo y significativo por estar expuestas a condiciones adversas, principalmente del clima y del tránsito vehicular, el cual aumenta juntamente con la densidad poblacional año a año, lo que genera un desgaste continuo en las propiedades físico-mecánicas del pavimento, llegando a convertirse en un inconveniente llegando a perjudicar la seguridad tanto para conductores como para caminantes. Por ello en este estudio se plantea una alternativa para contrarrestar el desgaste del pavimento incorporando microesferas de vidrio a la mezcla asfáltica en diferentes porcentajes, lo que podría significar un mayor tiempo de vida útil. Se ha realizado, de acuerdo a los objetivos, la caracterización de los agregados para el diseño de mezclas asfálticas en caliente con microesferas de vidrio; el diseño patrón para mezcla asfáltica en caliente con agregados naturales y para mezclas asfálticas experimentales con microesferas de vidrio en distintos porcentajes. Se han evaluado los resultados adquiridos de los ensayos de laboratorio realizados, determinando que el porcentaje óptimo de microesferas de vidrio es 10%. Además, se verificó el grado de reflectividad mediante la elaboración de una pequeña losa asfáltica conteniendo el porcentaje óptimo de microesferas. Siendo una alternativa valiosa para pavimentos urbanos de tráfico medio en la región, con la posibilidad de generar beneficios a base de costos y mayor vida útil de la infraestructura vial.
It is essential to recognize the importance of roads in human daily life and how necessary it is to maintain them in good condition. Roads are known to experience continuous and significant wear due to exposure to adverse conditions, primarily weather and vehicular traffic. This wear increases with population density year after year. This generates continuous wear on the physical and mechanical properties of the pavement, becoming a problem and impairing safety for both drivers and pedestrians. Therefore, this study proposes an alternative to counteract pavement wear by incorporating glass microspheres into the asphalt mix in different percentages, which could result in a longer useful life. In accordance with the objectives, the aggregates for the design of hot-mix asphalt with glass microspheres were characterized; the standard design for hot-mix asphalt with natural aggregates was developed; and experimental asphalt mixes with glass microspheres were developed in different percentages. The results of laboratory tests were evaluated, determining that the optimal percentage of glass microspheres is 10%. Furthermore, the degree of reflectivity was verified by creating a small asphalt slab containing the optimal percentage of microspheres. This represents a valuable alternative for medium-traffic urban pavements in the region, with the potential to generate cost benefits and extend the lifespan of road infrastructure.
