Mejoramiento de la vía de acceso entre las comunidades de Chilcapamba y Santa Marianita del cantón Mocha de la provincia de Tungurahua

Abstract

Due to the poor conditions of mobilization and vehicular access, in agreement with the Municipal GAD of the Canton, it is proposed to implement a solution to the problem by making a proposal to improve the road that connects the analyzed sectors. The work began with the topographic survey of the study area using a Trimble R8 RTK equipment, in order to determine the current conditions of the terrain. Followed by the study of the traffic in the Santa Marianita sector, where the existing current traffic volume was determined to later determine the future traffic. For the soil study, 8 samples taken by pits every 500 meters were tested, where the physical and mechanical characteristics of the soil were determined. Once these data were obtained, the geometric design of the road was carried out, based on the regulations proposed by the MTOP 2003. The structure of the flexible pavement was also determined by means of the AASHTO - 93 regulations, both the thicknesses of the base layers, sub-base and asphalt. The hydraulic design of the road was carried out, where the sections of gutters and sewers were defined. In addition, a reference budget of the project was elaborated by carrying out an analysis of unit prices.
