Diseño vial para la rectificación y mejoramiento de la vía arterial secundaria ubicada entre el km 0+800 y km 2+000, de “Santa Rosa Alta de Uyumbicho”, en la parroquia de Tambillo, cantón Mejía

Abstract

The project developed below has been carried out in order to obtain the optimal road design for the rectification and improvement of the secondary arterial road, located between km 0+800 and km 2+000, of "Santa Rosa Alta de Uyumbicho", Tambillo Parish, Mejía Canton, Pichincha Province, an alternative that implies all the socio-economic progress of the sector, therefore, the development of mobility, tourist, socio-cultural, agricultural, floricultural and livestock activities, as well as the direct connection with The Main Avenue "Colectora Quito - Tambillo" that allows the decongestion of the vehicular flow and therefore the road of the study problem is of great help to reduce the vehicular congestion. This rectification and improvement project implied previous field and laboratory studies. Firstly, field studies were carried out such as topographic survey, soil study, among which are: the extraction of undisturbed samples from the subgrade for their respective SUCS and AASHTO classification, behavior tests (DCP and CBR) and counting vehicle to carry out the projection of the useful life of the road. Subsequently, the geometric design was carried out by means of the topographic strips of the previous studies of the topographic survey, as well as the parameters and expressions provided by the MOP 2003 regulation, likewise the determination of the number of equivalent axes by means of the AASHTO 93 regulation, that allows to carry out the best alternative of pavement design, where the structural thicknesses of each layer of the pavement are detailed, in addition, the hydrological analysis was carried out, where the design of hydraulic structures that allow road drainage through ditches and sewers, as well as the respective investigation of road signs through the INEN Regulations that provide road safety, control and regulation of pedestrians and vehicles. The study of environmental assessment that is based on mitigating and preventing damage to the environment. And finally the determination of budget and costs, where the analysis of unit prices and the valued schedule of the project are determined, studies that allow recognizing the feasibility of the project to see if it is acceptable or not, through routine maintenance or period of via.
