Abstract

The strength under monotonic load, resilient modulus and rutting were evaluated on a hot asphalt mixture modified with a residue of polyvinyl chloride (PVC) by wet way. Additionally, the influence of environmental conditions of Bogotá D.C. was
evaluated during 21 months on mechanical properties of modified asphalt mixture. The results show that the mechanical properties evaluated were higher for the MDC-2 mixes modified with PVC compared with mixtures with asphalts without additives. The PVC produces higher penetration resistance and lower thermal flow
susceptibility. The general tendency of the mixtures is increase the modulus with time due to aging of the asphalt cement. However, mixtures with AC 60-70 and modified with PVC decrease stiffness in the first months due to thermal micro-cracks phenomena.
