Evaluación del comportamiento de mezclas elaboradas con RAP proveniente de desechos del instituto de desarrollo urbano y de la unidad de mantenimiento vial que están siendo aplicadas en vías rurales de Bogotá. Estudio de caso

Abstract

This document presents the results of a case study in which asphalt pavement residues (RAP) were applied to maintain some sections of the rural road network in the towns of Sumapaz and Usme in Bogotá. The auscultation of an initial pathology of damage is carried out, to which a series of laboratory techniques and work methodologies are applied for the management of project changes. The adjusted designs and processes were applied to the non-intervened sections and after two (2) years with exposure to the environment and traffic, the respective field and laboratory evaluations were carried out and the remaining mechanical condition of the mixture was measured through of Beam Benkelman deflections with their respective analysis with DEFLEX - IMPACO and EVERSTRESS modeling. With these experiences, new pavements were made, this time in the town of Usme where an improvement with micro-paving was incorporated, giving a contribution to the state of the art of this technology.
