Elaboración de un plan de mantenimiento de la vía comprendida entre los barrios Danzapamba y San José de Barba la Y desde la abscisa 0+000 hasta 5+000, cantón Pujilí.

Abstract

Given the advanced deterioration of the Danzapamba and San José de Barba la Y neighborhood roads, the current safety and road infrastructure standards do not meet the technical requirements necessary to guarantee their optimal serviceability, for which a comprehensive and sustainable maintenance plan is proposed. This responds directly to the urgent need for adequate, modern and efficient road infrastructure for the continued progress of the inhabitants to ensure their safety and that of road users in general. To establish an effective road maintenance plan, we began with a thorough assessment of the road's current condition. This critical stage involved techniques such as topographic surveying with the aid of a high-precision RTK instrument, as well as detailed traffic studies and laboratory soil analysis. The evaluation of the Pavement Index (PCI) complemented this information, allowing the existing deterioration to be quantified. With this data, an optimal structural package for flexible pavements was designed and a reference budget was prepared, thus ensuring an efficient and long-lasting road intervention. After a thorough analysis, it was established that the evaluated road has an extension of 5 km, which is paved in its entirety, and it is expected that in the next 20 years an average of 6792 vehicles/day will circulate on it. Considering these characteristics, the road was classified as a class I road. The soil studies indicated an average CBR index of 16.50 percent, classifying the soil as fair to good for subgrade use. Based on this data, the flexible pavement was designed with a thickness of 5 cm of asphalt layer, 20 cm of base and 20 cm of subbase, thus obtaining a value of 45 cm of structural package. Finally, an economic analysis was performed, resulting in an estimated total project cost of $685.945,65.
