Diseño geométrico y del pavimento de la vía Llangahua – Silipo – Pinllopata pertenecientes a las provincias de Tungurahua y Cotopaxi en el tramo km 8+000 – 12+000

Abstract

The road project addressing the connection between the Llangahua, Silipo, and Pinllopata communities, located in the provinces of Tungurahua and Cotopaxi, emerges in response to the identification of the need to establish a road connection. This approach aims to improve the living conditions of the inhabitants, reduce product transportation times, and foster social and economic development in the region. A rigorous topographic survey and soil studies were carried out, including Grain Size Analysis, Atterberg Limits, Modified Proctor, and CBR (California Bearing Ratio) analysis. The soil classification as non-plastic or low-plasticity clayey sand, along with a design CBR of 8.10 percent, laid the foundations for the planning of the pavement structure. Simultaneously, the traffic study determined a projected Design Traffic Volume (TPDA) of 94 vehicles/day for a 20-year design period, classifying the road as a Class IV Collector according to the regulations of MTOP 2003. The horizontal, vertical, and transverse design was adjusted in accordance with these regulations, ensuring its coherence with established parameters. Based on the information gathered about soil characteristics and traffic flow, the pavement structure was defined, considering effective thicknesses to ensure the functionality and safety of the road. Finally, as a result, the quantification of the work was carried out to obtain a reference budget for the technical project, providing a clear understanding of the necessary resources and facilitating precise planning for the execution of the proposal.
