Análisis para la obtención de límite líquido y límite plástico según la Norma ASTM D4318 en comparación con la norma BS 1377:1990 en suelos de diferente plasticidad.

Abstract

The experimental technical work presented below aims to perform a correlation between the methods used to obtain Atterberg Limits, contrasting between the traditional methods based on the ASTM D4318 Standard "Standard Test Method for Liquid Limit, Plastic Limit, and Soil Plasticity Index” and the methods used with a Cone Penetrometer based on the BS 1377:1990 Standard “Test Methods for Soils for Civil Engineering Purposes” and the book by Braja Das “Fundamentals of Geotechnical Engineering”, fourth edition. In addition, an uncertainty calculation process was carried out for each developed methodology, to obtain this purpose, a series of experimental tests were carried out on different samples, which were treated statistically, thus allowing the analysis of different statistical parameters and validation parameters. As a result of this work, it was possible to know the different alternatives and equipment that are currently used for the determination of the liquid limit and plastic limit, showing that the use of the Cone Penetrometer for the calculation of the liquid limit turns out to be feasible by means of this method. On the other hand, it was found that, for the calculation of the plastic limit, the traditional method is still the most appropriate.
