Correlación entre el CBR, DCP, las propiedades índices y mecánicas en los suelos de la parroquia Río Negro del cantón Baños de Agua Santa, provincia de Tungurahua

Abstract

The purpose of this experimental work aims to determine the correlation between the laboratory CBR and the index and mechanical properties of the soils of the Río Negro parish of the Baños de Agua Santa canton, Tungurahua province. To start with the technical part, the most representative roads of the parish were identified for taking soil samples, where pits were made removing the layer of vegetal soil. The field tests and the taking of samples of approximately 50 kg for each point were carried out for the different tests to be carried out in the laboratory, in which the AASHTO regulations were applied. According to the results obtained in the field and laboratory tests, the simple and multiple correlations were carried out, applying the regression analysis and the least squares method respectively. Acceptable correlations were selected, according to the determination coefficient that is greater than 50 percent. Finally, 30 correlations were found where the coefficient of determination varies between 52 percent and 92 percent, this means that the CBR of the correlations is close to the laboratory CBR, therefore, they can be used for the design of pavements. flexible.
