Influencia de las condiciones ambientales de la ciudad de Bogotá sobre la estabilidad y el flujo Marshall de una mezcla densa en caliente

Abstract

Influencia de las condiciones ambientales de la ciudad de Bogotá sobre la estabilidad y el flujo Marshall de una mezcla densa en caliente El artículo presenta el cambio que experimentan los parámetros de estabilidad y flujo del ensayo Marshall de mezclas asfálticas densas en caliente tipo MDC-2, cuando son expuestas al medio ambiente de la ciudad de Bogotá D.C. Las mezclas estudiadas fueron elaboradas y evaluadas empleando los dos cementos asfálticos (CA) típicos producidos en Colombia por ECOPETROL: CA 80-100 proveniente de la refinería de Barrancabermeja y CA 60-70 proveniente de la refinería de Apiay. Los parámetros de estabilidad y flujo de las mezclas fueron medidos cada tres meses durante un año con el fin de observar su evolución en el tiempo. De los resultados se concluye que el comportamiento que experimentan las mezclas depende del tipo de CA utilizado. Adicionalmente, la tendencia de las mezclas con ambos tipos de CA es experimentar aumento en los valores de estabilidad y flujo con el tiempo de exposición al medio ambiente

The paper presents the change that undergo the Marshall Stability and Flow of hot mix asphalts (type MDC-2) when they are exposed to weather of Bogotá D.C. The mixes were performed and evaluated employing the two typical asphalt cements (AC) produced in Colombia by ECOPETROL: AC 80-100 from Barrancabermeja and AC 60-70 from Apiay. Marshall Stability and Flow of the mixes were measurement each three months during one year in order to obtain its evolution with the time. The general conclusion was that the behavior of the mixes depends of the AC used. Additionally, the tendency of hot mix asphalts is increase the values of Marshall Stability and Flow when the asphalt mixtures are exposed to weather of Bogotá D.C.
