Optimización de la geometría de la vía desde el puente Yanayacu hasta Píllaro entre las abs 14+625-19+500 perteneciente a la provincia Tungurahua

Abstract

This technical project arises from the need to provide improved roads, safe and comfortable mobility to the inhabitants that covers between the abscissas 14+625 to 19+500 of the city of Píllaro. In addition, with the objective of reducing vehicular travel time and promoting economic development and tourism in the areas involved and their surroundings. The project was divided into three phases. The first consisted of field activities, such as the delimitation of the area and the topographic survey. A traffic study projected for 20 years was also carried out to establish the geometric characteristics of the road. In the second, soil samples were extracted that were analyzed in the laboratory to determine their physical and mechanical properties. Concluding with the optimization of the road following the indications of the MOP 2003 regulations, the calculation of the pavement structure and the preparation of a reference budget for the project. As a result, a total length of the road of 4,712 km was determined, with an undulating relief and not so steep slopes. In addition, a future TPDA of 4387 vehicles/day was projected, which classified the road as Class I. Subsequently, a sandy-silty soil with low moisture content and a design CBR of 20.70 percent was identified, indicating excellent quality for use in the subgrade. Based on this data, the pavement thicknesses were calculated, which were 7.5 cm for the asphalt layer, 15 cm for the base, and 20 cm for the subbase for the pavement structure. Finally, a reference budget of $1,899.616,41 was made for the execution of the project. This proposal will seek to improve connectivity and reduce vehicle time with adequate planning for the development of the technical project, thus contributing to the economic and social growth of the sector.
