Correlación entre el CBR, DCP, las propiedades índice y mecánicas en los suelos granulares de la parroquia San José de Poaló del cantón Píllaro, provincia de Tungurahua

Abstract

The aim of this research work is to determine the existing correlations between the laboratory CBR, DCP, of the Index and Mechanical Properties, of the parish San José de Poaló, For the execution of this project, samples were taken from 12 types of soils located on the main roads of the sector. After taking samples, field and laboratory tests are carried out to determine the different properties of the analyzed soils. Once data from the different tests carried out have been obtained, the most significant correlations between index and mechanical properties are determined, taking into account that these correlations help the optimization of time and resources on site, giving a total of 22 correlations taking between two and three variables. The reliability of these correlations varies between 50.25 percent to 97.53 percent, which is considered an appropriate degree of reliability. Regarding the determination of the CBR, it shows little variation, which is considered a good relationship with minimal errors because the real value calculated by means of laboratory tests indicates the same thickness of the different layers of a flexible pavement.
