    Abstract

    Although plastic limit, PL, is one of the parameters more widely used in the field of geotechnical engineering, the existing method for its determination (the thread-rolling test) is characterized by its low accuracy, repeatability, and reproducibility. These shortcomings have led to a great deal of criticisms, and in fact, several authors have tried to develop alternative methods to obtain the PL in soils. Despite that, the standardized thread-rolling method remains strong because of its simplicity, low cost, and quick performance. In previous studies, an alternative method, which was based on bending soil threads of 3 mm in diameter and 52 mm long until they start to crack, was presented by the authors. The relationship between the water content and the measured bending deformations allows the PL to be calculated with an equation. Apart from this, experienced laboratory operator. The Casagrande chart has been interpreted according to the PL, BL, and SSL in order to uncover more information about this system for soil classification, and after detecting some incongruities, a new proposal is presented.
