Abstract

"Liquid limit" is one of the most important properties used for classification of soil samples. However, up to now, the definition of this property along with their relevant methods of determination have not been unified yet. This paper attemps to introduce the evolution of methods of determination of liquid limit together with the interrelationship of liquid limits for cohesive soils obtained from these methods. The relationships of liquid limits from different methods are summarized from the researchs of authors since 1957 to 2001.
