Ampliación de la vía El Limón – el deseo tramo 12+000 a 16+000 perteneciente al cantón Pangua de la provincia de Cotopaxi

Abstract

Due to the fact that currently between the El Limón - El Deseo sector in the 12+000 to 16+000 section there is an average baseline of 3 m, making traffic difficult, we used the parameters standardized by the Ministry of Transportation and Public Works MTOP - 2003 and AASHTO regulations. For this purpose, data collection and analysis methods were implemented to determine the current condition of the road and to propose an adequate solution to improve the quality of life of the residents. To determine the orographic characteristics of the area, a topographic survey was used with an M3-DR2 total station along the road axis with a 50 m strip on each side. To determine vehicular traffic, we used the TPDA counting method with a 20-year projection, which allowed us to establish horizontal and vertical geometric and pavement structure design parameters based on MTOP and AASHTO guidelines. With the extraction of soils, it was determined that between sections 12+000 to 16+000 there is a predominance of clayey-loamy soil of medium to low plasticity based on the plasticity charts (SUCS) and AASHTO, in addition, the bearing capacity of the soil was determined by the CBR test, which determined a structure of 20 cm of sub-base, 10 cm of base and 5 cm of asphalt binder. With the quantification of cut and fill, a referential construction budget was determined with a value of $ 935,547.85 US dollars.
