Correlación entre CBR, DCP, propiedades índice y mecánicas en los suelos de las parroquias Guasaganda y Pucayacu del cantón La Maná, provincia de Cotopaxi

Abstract

The provinces of Guasaganda and Pucayacu belonging to the La Maná canton, being sectors far from the main axis, have roads that do not ensure correct vehicular circulation due to the lack of information on the properties of the soil. For this reason, the present research work seeks to expand the database of said soils and in this way determine a magnitude between the California Bearing Ratio (CBR) test and the Dynamic Cone Penetration (DCP) test, since they are factors that have a direct impact. with the design of flexible pavements. The investigative project consists of 3 phases where it started from a preliminary study of the area, the excavation of 12 pits and the extraction of approximately 50 kilograms, thus executing in situ tests such as the Cone and Sand and DCP in accordance with the stipulated regulations. Following this, the index and mechanical properties were developed through tests carried out in the laboratory, to later comply with phase 2, which corresponded to the determination of different correlations between tests, where a reliability coefficient of 55.68 percent was obtained in the compensation between CBR and DCP are a moderate range of acceptance. These CBR values obtained in compression and in the laboratory made it possible to apply them in two preliminary designs of the flexible pavement where it was verified that, since there was no greater variability in percentages, the pavement design consisted of the same thicknesses, 5 cm for layer. asphalt, 15 cm for base and 20 cm for subbase.
