Implementación del proceso de conservación de la estructura de la capa de rodadura vía Camino Real sector Huachi Grande – Montalvo en el tramo de la abscisa 0+000 hasta la abscisa 4+000 de la provincia de Tungurahua

Abstract

A country's roads are fundamental for its economic development, which is why governments have become aware of the need to develop and implement road conservation and maintenance plans to ensure that these roads fulfill the useful life for which they were designed. For develop the road maintenance plan for the section from abscissa 0+000 to 4+000 on the Camino Real Road in the Huachi Grande - Montalvo sector, a topographic survey, a traffic study, laboratory tests to obtain soil properties, and field tests to determine the surface and structural condition of the pavement and the bearing capacity of the subgrade were conducted. With the results obtained from the current and future traffic study, the road under study has the characteristics of a highway or AV1 multi-lane road, the type of soil found is clayey and silty gravel and sand (A-2-4 and A-2-6), with regular to good performance if used as subgrade (average CBR value of 9.83 percent), with good structural performance both in the subgrade and in the pavement, its deflection is type I, i.e. with a regular state of deterioration. Based on the results of the deflection (Benkelman Beam) and the Pavement Condition Index (PCI), the road maintenance plan is established, which consists of routine and periodic maintenance to preserve and maintain the structure of the wearing course for more years and avoid reconstruction before it reaches its useful life and causes dissatisfaction to users.
