Influencia del agua en mezclas densas en caliente Tipo 2 (MDC-2)

Abstract

Las principales causas del deterioro de mezclas asfálticas en una estructura de pavimento flexible son originadas por las cargas impuestas por el tráfico y los agentes ambientales. Con respecto a los agentes ambientales, uno de los principales modos de daño de mezclas asfálticas in situ ocurre cuando se separa el ligante asfáltico del agregado pétreo debido a la presencia de agua. El estado del conocimiento en esta área es que a pesar del alto número de investigaciones realizadas, este modo de daño y las causas que lo generan no han sido totalmente entendidas e identificadas. En este artículo se presenta la evolución en laboratorio del cambio en las propiedades mecánicas que experimenta una mezcla asfáltica densa en caliente tipo 2 (MDC-2) (de acuerdo con las especificaciones del Instituto nacional de Vías - INVIAS, 2007) y los cementos asfalticos (CA) CA 80-100 y CA 60-70 cuando son sumergidos en el agua durante un periodo de tiempo de cinco meses. La propiedad evaluada es la resistencia mecánica bajo carga monotónica de tracción indirecta mediante el ensayo Marshall. De los resultados obtenidos se concluye que esta resistencia disminuye cuando las mezclas asfálticas son sumergidas, mientras que las mezclas que son fabricadas con los cementos asfalticos sumergidos aumentan los parámetros de estabilidad y rigidez.
