Prediseño geométrico de la vía Pinllopata – El Corazón en el tramo 11+800 hasta 15+700 perteneciente al cantón Pangua de la provincia de Cotopaxi

Abstract

The project is located in the province of Cotopaxi, Cantón Pangua, Parroquias Pinllopata and El Corazón in Section 11 + 800 to 15 + 700. In the problem, the need for an adequate access road to improve the quality of life of the inhabitants was emphasized. The methodology used the parameters established by the Ministry of Transportation and Public Works MTOP - 2003 and the AASHTO. The methods used in the analysis and data collection allowed to carry out a study of the current condition of the road, and the rethinking of a new guide that complies with standardized regulations for its execution. The topographic survey was carried out with an RTK type GPS and a drone due to the mountainous area and steep terrain. A TPDA of 465 vehicles in both directions of traffic was determined for a design period of 20 years, defining it as a Collector, Class III road. The soil studies established that along the section 11 + 800 to 15 + 700 we are facing a sandy clay - silty sand soil, of medium to low plasticity according to the Unified Soil Classification System, and the AASHTO, considering the improvement from the subbase. Establishing the thickness of the flexible pavement structure of 10 cm of asphalt, 20 cm of base and 25 cm of subbase using the AASHTO – 93 Method.
