Análisis comparativo de suelo de campo y laboratorio para la medición de su capacidad portante con ensayos de Valor de Soporte de California (CBR) y Cono Dinámico de Penetración (DCP) en la Universidad Técnica de Manabí.

  The purpose of this investigation is to determine direct correlations by means of laboratory tests for the index of resistance to the cut of the Dynamic Cone of Penetration (DCP), with the resistance to cut California Bearing Ratio (CBR) of the soil, where it presents an alternative to establish Design criteria for pavement structures, based on physical and mechanical tests,  taking samples by means of soil exploration, they were subsequently processed in the laboratory demonstrating their properties where silts and clays with a high degree of plasticity predominate. Correlations proposed by (Van Vuuren, 1969) were taken, which experimentally mentions an equation suitable for all types of soils and the most accurate according to its reliability, the Dynamic Cone developed by (Scala, 1956), which, experimentally presents the following results in the field: The N°1 poll a 4.7% CBR, the N°2 poll a 3.61% CBR and the N°3 poll a 3.37% CBR, these mentioned parameters were obtained in a corresponding way from the DCP index of 40 mm/stroke, 50 mm/stroke, and 54 mm/stroke, in addition to laboratory tests that a more conservative parameter results were obtained for the poll N°1 a CBR of 3.98% the Poll, N°2 a CBR of 3.40% and the Poll N°3 a CBR of 3.20%.   Index Terms— Dynamic Cone of Penetration (DCP), California Bearing Ratio (CBR), Poll, Correlations, Test.
