Abstract

The paper presents the evolution of the resilient modulus, permanent deformation and strength under monotonic loading of a dense hot mixture due to long term exposure to the environment in the city of Bogota D.C. (Colombia). The mixtures were made using two asphalt cements (AC) and modified asphalt cement (MAC) with ethil-vinil-acetate: AC 80-100, AC 60-70 and MAC 20-40 respectively. The mechanical properties have been evaluated every three months over a period of 20 months for the AC 80-100 and AC 60-70, and 10 months for MAC 20-40. The results show differences depending on the type of cement. All mixtures increase the modulus with time due to aging of the asphalt cement.
