Análisis de las correlaciones entre el CBR, DCP, propiedades índice y mecánicas en suelos de la parroquia Pilaló del cantón Pujilí de la provincia de Cotopaxi

Abstract

This experimental work arises from the need to expand the database of soils that represent the areas of the Cotopaxi province to serve as support in the preliminary studies of flexible pavements, for which the main objective is to analyze the correlations between the laboratory CBR, DCP, and the index and mechanical properties in soils of the Pilaló parish of the Pujilí canton of the Cotopaxi province. For the present work, 4 third-order roads were chosen around the entire surface of the parish where 12 soil samples were taken, making pits of 1.50m x 1.50m and 1m deep, taking in each pit more than 30 kg of altered soil. of subgrade. Field and laboratory tests were developed to know the properties of the soils obtained, once their results were known, they were analyzed and 25 correlations were obtained where their R^2global correlation coefficient is between 56% and 99% What we want to argue that moderate to very strong correlations were obtained. The equations obtained from the correlation of the different properties serve as a guide for preliminary pavement designs since the tests with which the correlations were obtained serve primarily to evaluate the conditions of the subgrade of roads, bases and subbases, in addition to providing in the expansion of the database of the Ecuadorian territory with the zoning of the different soils found in the Pilaló parish of the Pujilí canton of the Cotopaxi province.
