Análisis de la aplicación de bases estabilizadas con capa de protección asfáltica en los plazos, costos y calidad de construcción en la vía Pindal-Milagros-Paletillas y su impacto en la red terciaria de la provincia de Loja.

Abstract

Currently, public institutions in the country, responsible for the maintenance of rural roads, seek options to optimize economic resources harmonized with the environmental balance; Asphalt emulsions meet these requirements, as effective solutions for the paving of rural roads with low traffic. In order to arrive at the object of this investigation, different types of rolling layers and their respective structures are compared under the criteria: initial investment per kilometer, effectiveness of the structure according to its annual equivalent cost and ease of maintenance. The application of asphalt emulsions with the stones of the sector is analyzed and through laboratory tests, cost analysis and comparisons of the different combinations of materials and asphalt emulsion to identify the impact of new paving alternatives. It is concluded that the cold asphalt mixtures with asphalt emulsion and stone aggregates of the area, generate an impact in the construction of pavements for rural roads of low traffic in the province of Loja, from the economic, environmental and productive point of view.
