Correlación entre el CBR, DCP, propiedades índice y mecánicas en suelos de la parroquia Alaquez y Joseguango bajo del cantón Latacunga, provincia de Cotopaxi

Abstract

The present research work belongs to a macro project that is being carried out in the province of Cotopaxi, which seeks to determine empirical equations through correlations between CBR, DCP and index and mechanical properties of representative soil samples from different parishes belonging to each of the cantons that make up the province of Cotopaxi, This is done so that these equations allow to obtain an approximate value of the properties of the soil, which would mean a saving of time and money in the realization of tests. This experimental work was developed through phases, starting from a preliminary study, where the study area was identified and the points from which the representative soil samples of the Alaquez and Joséguango Bajo parishes were extracted, based on that information the first phase was carried out that includes the execution of field and laboratory tests of the 12 soil samples extracted, followed by the second phase in which different correlations were determined between the soil properties found obtaining values of determination coefficients between 50 and 100 percent. Subsequently, a flexible pavement design was made for a rural road with the CBR obtained through the correlations and the one obtained in the laboratory. Finally, the studied samples were zoned and classified based on the results obtained through granulometry tests, Atterberg limits and SUCS and AASHTO standards.
