Recommended Procedures to Assess Critical State Locus from Triaxial Tests in Cohesionless Remoulded Samples

The critical state theory is a robust conceptual framework for the characterisation of soil behaviour. In laboratory, triaxial tests are used to assess locus. last decades, equipment and testing procedures characterisation, within framework, have advanced obtain accurate reliable results. This review paper summarises describes series recommended laboratory locus in cohesionless soils. For this purpose, results obtained from different soils configurations compiled, analysed discussed detail. presented reinforce use cells with lubricated end platens an embedded connection piston into top-cap, together verification full saturation condition measurement end-of-test water content—preferable using freezing technique. experimental evidence comparison between provide relevant insights about obtaining geomaterials. All herein can be easily implemented academic commercial geotechnical laboratories.
