Seguimiento a tramos de vía de bajos volúmenes con mezclas elaboradas con RAP provenientes de la UMV en la ciudad de Bogotá

Abstract

In the last twenty years, the study and use of Recycled Asphalt Pavement (RAP) in the construction and rehabilitation of pavements have grown due to its economic and environmental benefits. RAP contributes to waste reduction and decreases the demand for virgin materials. The focus of this thesis was the performance evaluation of RAP on a low-traffic volume road in the rural area of Bogotá. This road was treated with RAP sourced from the La Esmeralda production site of the Road Maintenance Unit (UMV). The recycled material underwent various tests, and a working formula was developed for its application on different roads. This phase was carried out in the initial stage of the research program. For the performance evaluation stage of the pavement under study, a road inventory system was employed, incorporating GPS receivers and high-definition cameras developed by the District University. During the evaluation, parameters such as pathologies, material quality, and construction processes were measured. The inspection compared these data with design standards, gathering information on construction and associated costs. The results contribute to understanding the behavior of RAP on low-traffic volume roads, providing a foundation for future decisions in the design and construction of sustainable pavements that promote the use of recycled materials in the road infrastructure of Bogotá.
