Correlación entre el CBR y las propiedades índice y mecánicas en suelos granulares, de las parroquias Atahualpa y Augusto Martínez, cantón Ambato, provincia de Tungurahua

Abstract

The present investigation is an experimental work to determine the correlation between the laboratory CBR and the index and mechanical properties of the granular soils of the Atahualpa and Augusto Martínez parishes of Ambato City. Tungurahua Province To carry out this work, a visit was made to the indicated parishes, identifying three secondary roads per parish, in each way two soil samples of approximately 50kg were obtained, collecting a total of twelve samples for the study of the properties of these soils. The correlations were made using results obtained with field tests such as DCP, Open pit, Field density (Ottawa cone and sand method) and laboratory tests such as Granulometry, Specific Gravity, Plastic Limit, Liquid Limit, Modified Proctor “B” and California Support Relationship (CBR). The correlations are obtained through statistical methods with least squares, applying to two and three variables. Where the best correlations were with the CBR. The results obtained from these correlations are applied in the pavement design, finding reliable CBR values.
