Methods of testing soils for engineering purposes Soil classification tests - Determination of the cone liquid limit of soil - One-point method
Standards Australia
This Standard sets out the method for determining the cone liquid limit of a soil using a cone penetrometer and only one measurement of moisture content. This method enables a result to be obtained when only a small amount of soil is available. The definition of liquid limit inherent in this method is not the same as that in the method using the Casagrande apparatus (AS 1289.3.1.1) although the values can be numerically similar (see Note 1).
NOTES:
1. Using the cone penetrometer, the one-point method is likely to give results that are less reliable than those obtained using the four-point method (see AS 1289.3.9.1) and is therefore suitable only where a less accurate result is acceptable.
2. If it is suspected that the liquid limit is higher than about 120%, the method specified in AS 1289.3.9.1 should be followed using the appropriate sample size.
