Correlación entre el CBR, DCP, propiedades índice y mecánicas en suelos de la parroquia Isinliví y Chugchilán del cantón Sigchos, provincia de Cotopaxi.

Abstract

This experimental work arises due to the limited existing information on soil analysis in the sector. Recognizing that such characteristics are crucial for the planning and execution of construction projects, a soil analysis was conducted in the parishes of Isinliví and Chugchilán, located in the Sigchos canton, Cotopaxi province. The results of this analysis will provide a comprehensive understanding of the existing correlations. To establish significant relationships, an exhaustive analysis was performed on 12 soil samples extracted from the study area. These samples were subsequently subjected to both field and laboratory tests. Once the results were obtained, they were tabulated and analyzed; this data allowed for the establishment of correlations between various soil characteristics, providing detailed insights into their properties.In the subsequent correlation analysis between the different tests, 22 significant correlations were identified, with determination coefficients ranging from Good to Excellent. Notably, the correlation between the California Bearing Ratio (CBR) and the natural moisture content yielded a coefficient of 72.27, which was utilized in the pavement design process. Finally, a traffic study was conducted in the area to formulate a flexible pavement design proposal. The CBR values employed were derived from both laboratory tests and those obtained through the correlations, confirming their suitability for application in the pavement design phase.
