The Measurement of Liguid Limit by the Dynamic Method

The apparatus for liquid limit determination by the dynamic method, is made for trial in our laboratory. The apparatus is shown in Fig. 1. The clay at several water content are contained in the vessel of apparatus and are grooved by the grooving tool. We defined that clay is in the dynamic liquid limit if 30 seconds vibration (Acc. 1400 gal) just closes the groove. The results obtained by this dynamic method are compared to the results of the standard liquid limits test.
