    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.
