Some problems in the previous test on liquid limit are clarified from the physical point of view in this paper. Among these, the two points of (1) operation of the apparatus usually used and (2) adjustment of remolded soils, must be considered when obtaining a flow curve. As measures for these, the Fall cone method and pF method have been suggested as new improved methods for replacing the conventional method.
The author proposed a new methed of determining liquid limit based on a new interpretation of liquid limit and explains the significance of remolded consolidation coefficient C'c=f (Lw)
