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

Abstract

The present experimental research work corresponds to a macroproject on correlations between the physical and mechanical properties of the soils of the province of Cotopaxi, by carrying out field and laboratory tests from representative soil samples, with the main objective of establishing empirical equations that, applied effectively, allow finding the properties of the soil based on other properties of the same in order to save time and money in carrying out essential tests for the design of pavements. The study area is included in the Sigchos parish belonging to the Sigchos canton, province of Cotopaxi, the experimental work was developed through phases, starting from a preliminary phase in which a technical inspection of the study area was carried out and established the sampling points, once the preliminary phase was completed, we continued with phase 1 in which the different soil tests were carried out in order to determine its index and mechanical properties, to continue with the phase 2 of carrying out the correlations between the results of the properties found, obtaining a total of twenty-four correlations with coefficients of determination between 68 and 98 percent, considered acceptable from 50 percent onwards. Finally, the results found from the laboratory CBR and the correlations are applied in the design of a flexible pavement for one of the roads studied, in order to demonstrate the applicability of the results of this experimental work.
