CPTu has proven to be an important tool with a multitude of uses throughout the life cycle of a ground improvement project, starting from design, execution and verification. The aim of this paper is to present several aspects of using the CPTu results in DC/DR ground improvement practice, including: exploration of pre-improvement sub-soil conditions, evaluation of the soil compactability and selection of the most suitable ground improvement solution based on CPT SBTn-Ic ranges, anticipation of the required compaction energy according to soil type and required level of ground stiffness. Several ground improvement case histories shall be presented to illustrate these different aspects.
