Correlación entre el CBR, DCP y las propiedades índice y mecánicas en suelos, de las parroquias Ulba y Río Verde, cantón Baños de Agua Santa, provincia de Tungurahua

Abstract

The present experimental work aims to find different correlations between the index and mechanical properties of soils belonging to the parishes of Ulba and Río Verde of the Baños de Agua Santa canton of the province of Tungurahua. To start the investigation, 12 soil samples were extracted from the four routes considered in the project. To obtain these values to be implemented in the process of correlation between the index and mechanical properties of the soils, both field and laboratory tests have been carried out in compliance with the different regulations established by AASHTO, ASTM and INEN for the execution in each study. After the evaluation and analysis process, the SUCS and AASHTO soil classification were determined, as the characteristics of each of the sample’s values, with which a total of 24 correlations were reached that exceed a coefficient of determination of 50 per cent, considering them as acceptable. Once the values of the laboratory soil support capacity (CBR) are known, such as that obtained by property correlation, we proceed to the design of the flexible pavement appreciating that the thicknesses of each layer are equivalent for each design. Because of the similarity between the CBR lab and CBR correlation.
