Correlación entre el CBR, DCP y las propiedades índice y mecánicas en los suelos de las parroquias: La Matriz y Pinguilí del cantón Mocha, provincia de Tungurahua

Abstract

This research refers to the soil analysis of the Mocha Canton, through the correlations of the California Bearing Ratio (CBR), Dynamic Cone Penetration (DCP), Modified Proctor, Liquid Limit, Plastic Limit, Granulometry, Specific Gravity, Density of Field, which allow us to know the index and mechanical properties of the soil. Once the sectors to be analyzed were identified, 6 routes were established for their analysis, obtaining two altered samples, making pits of 1.00m by 1.00m of variable depth at a distance greater than approximately 500m. In situ and laboratory tests were carried out, and based on the results obtained, 25 correlations were achieved between the different variables, applying statistical methods of simple regression and least squares, with a range of the coefficient of determination between 51 and 95 percent. considering themselves reliable. Finally, the flexible pavement was designed, using the CBR determined in the laboratory, and also the CBR calculated through correlations, obtaining the same thicknesses in both cases, confirming the reliability of the correlations made.
