El presente documento pretende dar a conocer cuál ha sido el comportamiento estructural y superficial que han tenido las vías construidas con mezclas asfálticas modificadas con grano de caucho reciclado de llanta (GCR) en algunos tramos de vía ubicados en las localidades de Bosa, Teusaquillo y Fontibón de la ciudad de Bogotá D.C. El punto de partida lo constituye la información suministrada por el Instituto de Desarrollo Urbano (IDU), ente encargado de la contratación y la supervisión de los trabajos de pavimentación con esta nueva tecnología de asfaltos modificados. El documento ha sido dividido en dos grandes capítulos, en el primero de ellos se relacionan las generalidades que incluyen el planteamiento del problema, justificación, objetivos y antecedentes sobre el tema de la aplicación de mezclas con asfaltos modificados con caucho, así como el marco legal que rige en nuestra ciudad para el diseño y la construcción de este tipo de pavimentos, normatividad existente etc. De otra parte un marco de referencia en donde se exponen los métodos de evaluación superficial y estructural utilizados para el desarrollo de esta investigación y un marco demográfico que sirve de guía y ubicación del contexto donde se desarrollaron los trabajos por parte de los contratistas del IDU. Por último se ha planteado un segundo capítulo de resultados en donde se plasma lo obtenido a través de las inspecciones visuales, mediciones y evaluaciones realizadas y análisis hechos a los resultados de los ensayos de laboratorio practicados, así como las conclusiones y recomendaciones dadas, posteriores a la experiencia. This paper seeks to highlight what has been the structural and surface behavior that have pathways built with asphalt mixtures modified with recycled rubber grain rim ( GCR ) in some sections of track located in the towns of Bosa, Gauteng and Fontibon city ​​of Bogotá The starting point is the information provided by the Urban Development Institute (IDU ) , the body responsible for hiring and supervising the work of this new technology paving modified asphalts. The document has been divided into two chapters, the first one including the general problem statement, justification , objectives and background on the subject of the application of mixtures with rubber modified asphalts are listed, as well as the legal framework prevailing in our city for the design and construction of this type of flooring , etc. existing regulations . Furthermore a framework where the evaluation methods used for surface and structural development of this research and a demographic framework that guides the context and location where work was performed by contractors IDU exposed . Finally it has raised a second chapter of results where the plasma obtained from visual inspections, measurements and evaluations conducted and analyzes made on the results of laboratory tests performed , and the conclusions and recommendations given , after the experience.
