Diseño de un plan de conservación de la estructura de la capa de rodadura de la vía Salasaka – Picaihua ABS 0+000 – 4+500 de la provincia de Tungurahua

Abstract

The roads, as well as their infrastructure, provide an indispensable base worldwide in order to provide the functioning of all economies. Its extension includes millions of kilometers, which is why it is essential to adequately preserve the respective infrastructure, this in order to preserve and increase the economic, social, and cultural benefits, among others. The Tungurahua Road network leads to being one of the fundamental pillars for the promotion of productivity, for which the generated project provided a maintenance plan for the study road, in which technical studies were carried out such as the lifting of the via georeferencing, the study of vehicular traffic, as well as the respective standardized soil and field tests to determine the condition of the pavement on the road. It was concluded, calculating in the traffic quantification, that the road under study is classified as a type II collector which is located on an excellent subgrade according to 21.61 percent of the CBR, composed mainly of silty sands with poorly graded gravel in terms of its structure. It was calculated that the road under study is in poor condition with a rating of 35.87 points based on the PCI and presented type III deflections in the asphalt layer. A maintenance plan was proposed, according to the damage to the road, providing solutions that allow its conservation and rehabilitation, with a budget of 624,668 dollars and 38 cents.
