Abstract


Objectives: The principal objective of this study is to contribute towards the possible replacement of the conventional techniques by implying geoelectrical technique which is an attractive tool for depicting sub surface soil profile to study the relationship between Laboratory Electrical Resistivity (LER) and Bulk Density (BD) of compacted laterite soil. Methods/Statistical Analysis: This research study is based on laboratory investigation of laterite soil properties and its relationship with electrical resistivity values. Findings: Beside some inconsistencies observed, the present study also reveals some significant results by showing a decreasing trend between electrical resistivity and BD for 40 soil samples. Application/Improvement: Laterite soil engineering properties are usually investigated through borehole sampling by employing heavy machinery, which affects the cost of the project and took too much time in the completion of the projects. Therefore an alternative, quick and less cost involved method is needed for soil investigation. Electrical resistivity technique is one of the most popular method which can be used for detailed soil investigation as being a cost effective, time saving and less effort involved method.
