Specifications in European countries include a variety of methods for determining the liquid limit based on Casagrande type devices and on the fall cone penetrometer. The results of a comparative study of the liquid limits determined using these two fall-cone methods are presented for lime stabilized soil. Soil material sampled in the area of Evros Regional Unit has been stabilized with lime in order to enhance its engineering characteristics. The soil and the soil-lime mixtures subjected in Atterberg limit testing. The liquid limit values were correlated through a linear regression analysis with the rest of the consistency limits of both the natural soil and its mixtures with various lime contents. The correlation coefficients in all cases were high, with those referring to results obtained by the Casagrande method to be dominant. The comparison of liquid limit values determined by either method showed that there is a systematically good correlation between them, with the decrease rate in function of the lime content in the mixture to be more intense in the case of the drop-cone procedure. There is a need for a universal specification for the determination of the consistency limits.

The Impact

The research presented in this paper aimed at the determination of the impact of a test method on the liquid limit of the selected cohesive soils with different content of clay fraction: loosely cohesive – clayey medium sand, moderately cohesive on the border of loosely cohesive – coarse silt and firmly cohesive – silty clay. Liquid limit was determined by the following methods: Casagrande, Vasiliev and the cone penetrometer. It was stated, that the values of the liquid limit of the tested soils determined by various methods were different, which significantly affected the assessment of their plasticity and consistency. According to the standard PKN-CEN ISO/TS 17892-2:2009, the liquid limit should be determined with the cone penetrometer, whereas the alternative is Casagrande’s method. The conducted tests showed, that in the case of cohesive soils containing up to 10–11% of clay fraction, the differences between the values of the liquid limit determined with the cone penetrometer and the Casagrande’s method were relatively small and equaled 1–2%, therefore both methods are correct. In the case of cohesive soils containing more than 20% of clay fraction, differences between the values of the liquid limit determined with the cone penetrometer and the Casagrande’s method were slightly higher than in the previous case, and equaled approximately 4%. In those cases, determination of the liquid limit can be performed both using the first or the second method, though the above-cited standard recommends the cone penetrometer method.
