Abstract

Geotechnical investigation is a crucial exercise in availing ground characteristics for safer and economical design and construction of infrastructures. In-situ testing for geotechnical investigation: such as Cone Penetration Test, when adopted to supplement field sampling and Laboratory tests offers economic benefit in terms of time saving and reduced cost for investigation. It is proven that dynamic cone testing offers additional benefits over static cone testing. Intensive research conducted for static cone testing has enhanced its accuracy for ground characterization. There are observed potential benefits of Light cone dynamic testing for shallow depth investigations (to 10 m depth). This review paper is aimed at exploring the information available on equipment specifications, standardization, application and interpretation models/monographs. The review has presented the gaps available in order to enhance predictability power of dynamic light cone penetration test. Furthermore, the review directs the focus on research in advancing the predictability power of the test.
