Summary: | The samples obtained from a site investigation are often disturbed. A condition that result in false lab results, which underestimate the real value. A correlation provide a lower bound against which the results obtained from lab tests can be compared. This is useful in offsite site investigation where obtaining high quality samples are expensive and difficult to acquire.
The objective of this study is finding the relationship between shear strength at plastic limit (PL) and liquid limit (LL), and to understand the behaviour of electrical resistivity with other properties such as; PL, LL, particle size distribution (PSD) represented as sand percentage in the sample, and shear strength (Cu).
To find the correlation required the shear strength at plastic limit was measured using vane shear test. Liquid limit and plastic limit was measured using cone penetration test and thread rolling method respectively. The PL and LL were represented as a percentage of the mass of moisture over the mass of solid. Moreover, the electrical resistivity was measured theoretically by obtaining resistance. Finally, the particle size distribution was measured using the hydrometer test and determined by the particle size distribution of sample size.
