    Correlación entre el CBR, DCP, propiedades índice y mecánicas en suelos de la parroquia Poaló del cantón Latacunga, provincia de Cotopaxi

    The parish of San José de Poaló, being in the rural area of the Latacunga canton, province of Cotopaxi, has a low development in the road infrastructure, having roads in very poor condition of the asphalt folder or need improvement since they are ballast or paved, which the inhabitants of the area, being mostly farmers and ranchers, find it difficult to transport their products for sale. The experimental work consisted of locating in the area of the parish the most representative roads which cover a large part of it, where 4 third-order roads were established where a total of 12 samples of 50 kg were extracted, later at each point the DCP and field density tests were carried out. In the laboratory, through the use of the necessary equipment and tools, the properties of the index and mechanical soils were determined, as well as the Modified Proctor and CBR to expand the database of the correlations of the soils in the area using simple and multiple correlation methods, in addition to the aforementioned results, they were used in the design of a flexible pavement following the AASTHO 93 standard. As results, 20 simple and multiple correlations were obtained where they had a coefficient of determination greater than 50 percent, being accepted, later with the use of the free software AASHTO 93, the thicknesses were calculated obtaining: 7.50 cm asphalt layer, 15 cm base, 20 cm subbase.
