Rediseño geométrico y diseño estructural de pavimento de la vía Belen Cuatro Esquinas – Bellavista de Cusubamba desde la abscisa 0+000 – 5+000, ubicada en la parroquia Cusubamba, cantón Salcedo, provincia de Cotopaxi

Abstract

In recent years, Ecuador has tried to improve its competitiveness compared to other countries in its road infrastructure, however, not all areas of the country have managed to optimize their road network. Without going any further, the quality of the Cotopaxi Road network has been overshadowed by its neighboring provinces, which is why the need arises to address new projects that contribute to the evolution of the infrastructure. To contribute to this objective, road studies were carried out following the processes dictated by the MTOP 2003 regulations. Starting with the survey of the topographic strip using an RTK device that revealed that the road was in mountainous terrain. The traffic study indicated that the TPDA for a design period of 20 years would be 778 vehicles/day, classifying the road as a CLASS III collector. With this information, the geometric redesign was carried out, adjusting the existing road to a new layout that complies with the parameters suggested by the standard and also without exceeding very large cut and fill areas. The structural package was designed based on the AASHTO-93 Method using the design CBR obtained in the soil study, finally the minimum and recommended thicknesses for subbase, base and asphalt layer are configured. Finally, the road design proposal was evaluated, and an estimated budget was developed, providing a clear view of the resources required and facilitating accurate planning for future project implementation.
