Análisis de las correlaciones entre el CBR, DCP, propiedades índice y mecánicas en los suelos de las parroquias: la victoria y Pujilí, cantón Pujilí, provincia de Cotopaxi

Abstract

The lack of information on the type of soil in a place slows down the construction process, so expanding the database of roads guarantees a guide for the preliminary design of pavements. The present experimental work aims to determine the correlation between the CBR, DCP, index and mechanical properties of the Pujilí and La Victoria parishes, belonging to the Pujilí canton, Cotopaxi province. The tests carried out in the field were: field density (cone and sand) and DCP, while the laboratory tests with a sample of approximately 50 kg for each point were: Atterberg limits, specific gravity, moisture content, granulometry, compaction and CBR. Each of these tests were carried out in accordance with AASHTO standards. Once the results of the respective field and laboratory tests were obtained, the analysis of both simple and multiple correlations between the different soil properties was carried out in order to determine the soil characteristics. Finally, a traffic study was carried out for the structural design of the flexible pavement of one of the roads where representative soil samples were taken. The CBR values used were those obtained from the laboratory and from the correlations obtained.
