    The study focuses on determining the permeability of course and fine aggregates, evaluating their potential use for applications in drainage systems. The permeability coefficient of the "Mina Mora" quarry was determined. Three phases were developed to help achieve the main objective of the project. The first phase, called exploratory, consisted of a visit to the quarry to collect essential information such as the georeferencing of the quarry and the obtaining of representative soil samples. In the second phase, the extracted soil was characterized using specific tests: natural moisture content, Atterberg limits, and granulometry. The soil was characterized according to the SUCS classification as a poorly graded sand (SP) and poorly graded sand with the presence of silt (SP-SM), presenting a low moisture content with an average of the samples of 1.98 percent and being a soil with zero plasticity in its majority. Finally, in the third phase, the experimental phase, the aim was to determine the permeability value of each of the samples, dividing them into coarse aggregate, sand, and silt. To find its permeability value, the constant load permeability test was chosen, using the Edibon brand Drainage Permeameter equipment. This equipment allowed us to obtain the permeability coefficient k (cm/s). As a result, it was obtained that the aggregates from the Mina Mora quarry are suitable for use in drainage works.

    Análisis experimental de la capacidad filtrante de drenaje de agregados pétreos provenientes de la cantera Playa Llagchoa y/o salvador, ubicada en el km7 vía a Aguaján, parroquia Santa Rosa, provincia de Tungurahua

    In the field of civil engineering, the filtering capacity of stone materials is of vital importance for the design and construction of efficient drainage works. The experimental work focused on investigating the permeability of the aggregates from the Llagchoa/Salvador Beach Quarry, located in the Tungurahua province. A survey of documentary information on the quarry was carried out and representative samples were collected for laboratory tests. Different tests were carried out to evaluate the physical properties, such as moisture content, Atterberg limits and granulometric analysis. Subsequently, by using a drainage permeameter with the constant head method, the permeability coefficient of each type of soil (gravel, sand, and silt) was obtained. The results indicated that the aggregates had a medium to high filtration capacity, with silt having the lowest permeability. Finally, the optimal drainage combination was sought, to estimate the filtration capacity of the soil, resulting in the most appropriate with a permeability coefficient of 4.06x10 raised to at least 2 (m/s) being the same permeable which makes it suitable for use in civil engineering projects related to drainage. This study provides valuable information for the design and construction of effective drainage systems, thus contributing to the development of more resistant and sustainable infrastructures, being useful for professionals in the field of engineering and for those interested in improving water management in civil works.

    Análisis experimental de la capacidad filtrante de drenaje de los agregados pétreos provenientes de la mina Los Moelles ubicada en la parroquia San Andrés, cantón Píllaro, provincia de Tungurahua

    Due to the diversity of voids, sizes and shapes, as well as the complex distribution of the soil, the flow of water through its mass is more complicated than through a tube or hole. To facilitate drainage, it is preferable to have a permeable soil. This study determined the physical properties of the soil, such as: Moisture Content, Atterberg Limits, and Granulometry. Using the AASHTO method, the soil is classified as Gravels and Silty or Clay Sands A-2-4 (0), while, by the SUCS method, soil samples 1, 3, and 4 are classified as poorly graded sand with silt with SP-SM gravel, sample 2 as poorly graded sand SP, and sample 5 as Poorly graded sand with SP-SM silt. For this purpose, a constant head drainage permeameter was used to determine the coefficient of permeability of the gravel, sand and silt of each sample. The results obtained indicate that the coarse aggregate has a high degree of permeability; the fine aggregate, a degree of medium permeability; and silt, a low degree of permeability. Finally, different combinations with different percentages of aggregates were carried out, concluding that the most efficient mixture contains coarse gravel, sand and fine gravel, with a medium degree of permeability, being within the range of permeable soils as established by the FAO.
