Correlación entre el CBR, DCP y las propiedades índice y mecánicas en los suelos de las parroquias: Patate (la matriz) y el triunfo del cantón Patate, provincia de Tungurahua

Abstract

The following degree project is part of a macro research that is being carried out in the province of Tungurahua, taking into account the parish and cantonal division, which seeks to determine correlations among the different index and mechanical properties of the soil, considering mainly the DCP test and CBR, in order to obtain the same results as the CBR, but in less time and cost through the DCP test. The tests are determined from soil samples collected in the La Matriz and El Triunfo parishes of the Patate canton, Tungurahua province. The tests carried out are: Atterberg limits, specific gravity, granulometry, compaction, CBR, field density with the Otawa sand cone method, and the dynamic penetration test; With the obtained results from the aforementioned tests, they are analyzed, determining the type and characteristics of the soil. Next, 23 correlations were obtained, applying statistical methods of simple regression and least squares. These correlations ranged from acceptable to excellent, with coefficients of determination between 50 and 99 percent. Finally, the design of the flexible pavement was carried out, using the CBR obtained in the laboratory, and also, based on the CBR of the proposed correlations. Obtaining the same characteristics in both designs, it is confirmed that the correlations are acceptable and can be used for the pre-design of asphalt on similar soils.
