Diseño geométrico de la vía que une el sector Pindo Mirador y La Colonia 24 de Mayo perteneciente a la parroquia Mera del cantón Mera, provincia de Pastaza

Abstract

Given the lack of a road connection that helps improve the economic and social situation of the population of the Mera canton and its surroundings, the geometric design of a road that connects the communities of the Pindo Mirador Sector was developed in the province of Pastaza, Mera canton. and Colonia 24 de Mayo, in order to improve the transportation and marketing of products. To identify the characteristics of the terrain, a topographic survey was carried out with a total station, which provided specific points along the path of the road to be designed. Subsequently, the vehicle flow was studied by manual counting for 7 days from Monday to Sunday, 12 hours a day, which allowed the calculation of the Average Daily Annual Traffic (TPDA) and obtaining a value with a 20-year projection equal to 192 vehicles per day. The study of the soil was done by means of excavations of test pits with sections of 500 meters and the determination of the Relative Value of the Soil Support Capacity (CBR) of design equal to 3.8%, but for the calculation of the thicknesses of the soil layers. flexible pavement applying the AASHTO-93 Estándar I was used 15% because it is the value of better subgrade. Finally, the geometric design of the road was developed applying the standard of the Ministry of Transport and Public Works (MTOP), which establishes that it is a Class IV road for the horizontal, vertical and transversal design, as well as for the radii, slopes, ditches, cut and fill volumes, which were made with the Autodesk software. The referential budget was obtained with the calculation of work volumes and analysis of unit prices referenced in the busy guide system called Punis of the Provincial Decentralized Autonomous Government of Pastaza (GADPPz), allowing to know that the total value of the work is two million one hundred fifty one thousand eight hundred fifty with 22/100 cents.
