Análisis de las correlaciones entre el CBR, DCP, propiedades índice y mecánicas en suelos de las parroquias: San Juan de Pastocalle y Tanicuchí del cantón Latacunga, provincia de Cotopaxi

Abstract

The lack of soil analysis in rural populations, either due to its high execution cost or inaccessible conditions of the land, lead to the following experimental work carried out in the parishes of San Juan de Pastocalle and Tanicuchi, province of Cotopaxi, corresponding to determining correlations between the California Bearing Ratio (CBR) and Dynamic Cone Penetration (DCP) tests, as well as with the index and mechanical properties of the soil, as an alternative to the pre-design of pavements. The trials were determined from 12 soil samples collected in the study area, San Juan de Pastocalle and Tanicuchi parishes of the Latacunga canton, Cotopaxi province. Where rectangular pits of 1.00 m x 1.00 m and 1.00 m deep were made, from which altered samples were extracted to be later analyzed in the laboratory. Then the results were tabulated and interpreted, obtaining adequate correlations between the index and the mechanical properties of the tested soils, with acceptable correlation coefficients and a good degree of reliability. 28 correlations were obtained with a correlation index between 52 to 95 percent. Finally, a flexible pavement was designed, based on the CBR obtained in the laboratory, and also based on the CBR calculated by the correlations, confirming the reliability of these correlations made and affirming that these data can be used for the pre-design of subsequent pavements.
