Evaluation of load-deformation characteristics of geomaterials is very essential and this is commonly obtained by conducting one-dimensional compression test using standard oedometer. However, only limited stress can be achieved using standard oedometer and many geomaterials particularly in the natural state require high stress. A floating ring oedometer has been designed, fabricated, assembled and used for testing clay for evaluation. This was achieved using steel and polymeric materials and fabrication tools. A vertical stresses of up to 20 MPa can be achieved in this new apparatus and can be used for both natural and reconstituted geomaterials. The new apparatus is comparable to standard oedometer based on evaluation.
