Study of Recycled Material for Repairing Cracks and its Application on a Pavement in Bogota, Colombia

Abstract

The article stems from the Sustainable Mobility project carried out at the Research Center for Sustainable Development and Climate Change (Cidescac) from La Salle University. Some nonbiodegradable materials were studied that could be recycled and reused as fissure sealants in asphalt pavements. The recycled materials were rubber from the used tires of vehicles and polystyrene (styrofoam) to improve the physical, mechanical and chemical properties of the asphalt mix. The tests performed included the physicochemical characterization of materials to find the optimum proportions of field application. Tests were analyzed in order to find chemical stability, plastic deformation, fatigue and the dynamic module of the designed mix. The scope of this phase of the research is the production, placement and follow-up of the new material to repair surface damage in flexible pavement, for which a test stretch granted by the Urban Development Institute was carried out
