    Análisis comparativo del material proveniente de las minas: “Kumochi”, “Los Muelles” y “Cantera El Salvador” del cantón Ambato utilizado para la elaboración de base y subbase en la construcción de carreteras
    (Universidad Técnica de Ambato. Facultad de Ingeniería Civil y Mecánica, Carrera de Ingeniería Civil, 2023-03) Aldas Ramos, Alexis Emilio; López Arboleda, Alex Gustavo
    Due to the state of the roads of the Ambato Canton in general, the initiative arose to study in depth the construction of the same, since the construction process of a road generally involves three layers, which in turn are composed of material from the different qualified mines of the canton. From the material selected from these mines, samples of fine aggregate (washed sand) and coarse aggregate (screened gravel) were taken with which laboratory tests were carried out that determined their index properties (natural humidity, Atterberg limits, granulometry, modified Proctor and relative density), the California Bearing Ratio test to determine the bearing capacity, tests to determine the physical and mechanical properties (strength of the aggregates and resistance to abrasion) and the assay to determine the percentage of fractured faces of the coarse aggregate; where the material of the mine "El Salvador" was as the one with better characteristics in addition to having a lower cost per cubic meter; however, the aggregates from the "Kumochi" and "Los Muelles" mines also met the quality standards stipulated by the Ecuadorian Road Standard; In addition, the aggregates of all the mines presented normal values according to their type.
