Implementación de un plan de conservación y mantenimiento de la vía Artezón Valle Hermoso, desde la abscisa 0+000 hasta la abscisa 4+100, ubicado en el sector Artezón, cantón Pelileo de la provincia de Tungurahua

Abstract

The implementation of a conservation and maintenance plan for the Artezón Valle Hermoso stretch of road was carried out because it presented several physical (potholes, cracks) and structural (pavement) problems, and also affected the mobility of the inhabitants of the sector, which is a productive sector. In order to carry out this technical project, soil samples were taken every 1000 m along the road under study and different properties of the road were determined, such as: granulometry, liquid limit, plastic limit, plastic index, soil bearing capacity, etc. In addition, a visual inspection was carried out using the pavement condition index, the result of which determined that the physical condition of the road was in a bad range, in addition to this, the deflections of the road were analyzed using the Benkelman beam, with these the behavior of the wearing course was obtained, which was also bad. Having made these calculations, and based on laboratory tests, it was concluded that the most appropriate maintenance for the road was a reconstruction, and we proceeded with the design of the pavement structure in which we obtained an asphalt layer of 5 cm, a class III base of 15 cm and a class III subbase of 15 cm. Finally, a referential budget was made to carry out the proposed reconstruction according to the maintenance plan, which was $411,936.34.
