Abstract

Liquid limit, plastic limit and the plasticity are used extensively, either individually index are used extensively, either individually or together with other soil properties, to correlate with the engineering behavior such as compressibility, permeability, compactibility, shrink-well characteristics and shear strength. In this study, the liquid limits of five soil samples from the Albay province were determined using the Casagrande method, and the plastic limits by the thread rolling method. The values obtained were compared with those obtained by the drop-cone method. The liquid limit by the Casagrande method obtained a smaller correlation coefficient (R²) than that of the drop-cone method. A higher R² is considered reliable and acceptable. The method also implies easier work on the data gathering and is more repeatable.The thread-rolling method resulted in plastic limits of statistically unacceptable values. The drop-cone method of obtaining the plastic limit was faster since the data gathered from the liquid limit can be used to evaluate its plastic limit, limiting the work done and with a statistically adequate result.It is necessary to establish standard methods that can be easily used by researchers, scientists and engineers to determine soil consistency limits. Further study should be done to support the claim that the drop-cone method is more reliable than the Casagrande method.
