Evaluación de las propiedades mecánicas de una mezcla densa en caliente modificada con asfaltita

Abstract

El trabajo evaluo en laboratorio la resistencia mecanica bajo carga monotonica, el modulo resiliente y la resistencia a la deformacion permanente que experimenta una mezcla asfaltica cuando se modifica con una asfaltita. Adicionalmente, fue evaluada durante dos anos, la influencia del medio ambiente de la ciudad de Bogota D.C., sobre las propiedades mecanicas de la mezcla modificada. Se concluye que la resistencia mecanica de la mezcla asfaltica modificada incrementa en comparacion con la convencional. La tendencia general de las mezclas con el tiempo de exposicion al medio ambiente de Bogota D.C., es experimentar un aumento en los valores de rigidez debido principalmente a procesos de endurecimiento por envejecimiento del ligante asfaltico. Sin embargo, para el caso de las mezclas modificadas y fabricadas con CA 60-70 en los primeros cinco meses de exposicion, la rigidez disminuye.
