Investigación de la imprimación reforzada para la conformación de capas de rodadura de caminos rurales de bajo tránsito

Abstract

The availability of adequate transport routes is essential to promote local development and quality of life of its residents, so the Autonomous Decentralized Provincial Government of Morona Santiago considered the use of the reinforced primer to improve the viability of roads in rural areas. Thus, in this work, was analyzed the alternative of reinforced primer as a rolling layer for make viable rural roads axes, taking into account that four road projects in the Province of Morona Santiago were analyzed (Amazon backbone - Mutinsa, Amazon backbone - Bellavista, access to Camal Mendez, and the route along the runway Patuca) evaluating the relation the cost / benefit of this alternative compared to unpaved roads.The material of the subgrade and materials that make up the existing structure were tested (granulometry, Atterberg limits, abrasion, modified Proctor and the bearing capacity of the structure (CBR)) and classified, and transit conditions were determined (TPDA, Number of Equivalent Axles, number of heavy vehicles) for a period of design. All these data allowed to determine the design of said structure. The cost / benefit ratio was evaluated by calculating the Cost Global Updated (CGA) for a period of analysis of 10 years, it was determined that the routes reinforced primer are more beneficial not only for cost savings, but also because they provide a comfortable surface, increased durability, reduce dust and improve the quality of life of the surrounding residents.
