Abstract

This technical project was developed to establish a road improvement of "San Alfonso" street, located in the Province of Pichincha, Canton Mejia, Parish of Alóag, with a length of 2.5 km, where the road helps the economic, agricultural and livestock development, it is also considered as an alternative road with the connection to the city of Machachi. For the study of the project it was necessary to carry out several studies in the field and laboratory. At the beginning, the respective topographic study was carried out, in addition to the vehicle count for 7 days, during 12 hours where the vehicular traffic was determined, also the soil study was carried out, where soil pits were extracted every 600 meters with a depth of 1.50 m, establishing the tests as: AASHTO classification, SUCS and Modified CBR. Next, the geometric design of the road was developed through the topography of the project, following the recommendations of the MOP 2003 and AASHTO 93 standards, which will help us design the pavement structure, as well as the hydraulic study with the design of the ditches and sewage to avoid flooding on the road, the respective analysis of the road signs was also carried out, where the locations of the vertical and horizontal signs were established. In addition, the environmental evolution was dealt with, where the environmental impact that the project to be executed will produce was determined and finally the respective budget, valued chronogram and VAN and TIR calculation were made to establish whether the project is feasible or not accepted.
