The paper presents observations made in CPTs performed under controlled laboratory conditions in normally consolidated clay–sand mixtures at various penetrations. These results are combined with data from field tests to develop a relationship for CPT data in young normally consolidated soils that combines end resistance and friction sleeve data. This relationship can be used to assist assessment of soil type and CPT parameters for un-aged normally consolidated soils as well as allowing judgements to be made in relation to likely levels of under-consolidation, structure and over-consolidation in any given soil deposit.
