Propuesta de mejoramiento de la vía que conecta la feria de ganado Píllaro con el puente del Río Cutuchi tramo km 0+300 – 4+300 de la parroquia Presidente Urbina, cantón Píllaro de la provincia de Tungurahua

Abstract

The road connecting the Río Cutuchi Bridge to the Píllaro Livestock Fair is in poor condition, primarily due to significant pavement deterioration caused by inadequate maintenance. This issue reflects a broader challenge in Ecuador, where similar infrastructure problems affect road safety, transportation efficiency, and regional connectivity. This study proposed an improvement and maintenance plan to address these challenges. Field activities included traffic analysis, topographic surveys, and laboratory soil testing. Tests such as CBR, Modified Proctor, Natural Moisture Content, Liquid and Plastic Limits, and Condition Index (PCI) analysis provided a detailed evaluation of road performance. The results showed that seven of the fourteen sections surveyed were in poor condition, with "Alligator Cracking" as the most common defect, observed in twelve sections. Rehabilitation or replacement of the asphalt layer was recommended for these segments. Five sections were classified as good, requiring routine maintenance, while two were in fair condition, needing periodic corrective actions and surface reinforcement. The study highlighted the need for immediate intervention to restore the road’s structural and functional integrity. The proposed solutions aim to enhance safety, improve traffic flow, and extend the road’s service life. The total estimated cost for the proposed interventions was $1,478,085.62, including rehabilitation, resurfacing, and maintenance activities. This project underscores the importance of timely maintenance and effective engineering solutions to address recurring infrastructure challenges. By implementing the proposed plan, the road will support safer, more efficient transportation and contribute to economic development in the region.
