Mejoramiento del diseño geométrico de la vía que une los sectores de Cruz Loma- Palama, ubicada en la parroquia Salasaca y el Rosario del cantón Pelileo, provincia de Tungurahua

Abstract

The development of a country or region depends to a greater extent on the condition of its roads, for these reasons it is essential to improve the roads, which will boost the productive and economic part of the sector under study influencing a better mobility of products and vehicles to travel along the road ensuring fluidity of communication between the beneficiaries. The present technical project starts with the observation in the territory of the current condition of the road, consequently we proceeded to the survey of the topographic strip where the road will be located, then we established the vehicle counting station where the volume of traffic was recorded for seven days for a period of eight hours obtaining the TPDA Annual Average Daily Traffic and the projection of future traffic in 20 years was established, The soil was also studied by means of moisture, granulometry, liquid and plastic limit, modified proctor, and the bearing capacity of the soil was determined by means of the CBR test. Subsequently, the horizontal, vertical and transversal geometric design was carried out in accordance with the regulations established by the Ministry of Transportation and Public Works, the flexible pavement design was obtained by means of the AASHTO-93 regulations, where the thicknesses adopted for the asphalt layer, base and subbase were specified. Finally, the cost of the project is specified through the analysis of unit prices.
