AB  - Deep geological disposal designs for nuclear waste often include an engineered barrier to protect the waste canistersand prevent leakage. The long-term safety of the repository relies on studies of the buffermaterial.Oedometer tests provide values ofdesign parameters fornumerical simulations. Anewly-developed oedometer with automated suction control is presented to assist in the investigation of the coupled hydro-me-chanical-volumetric  behaviour  of  an  expansive  clay,  namely  a  natural  sodium  bentonite. The  displacement-controlled  device  was  developed  to  apply  suctionover  a  range  of10  MPa  to  300  MPausing  a  divided-flow humidity-generator. The  device allows the application of combined stress and suction states, and continuous stress paths of constant volume, stress or suction. The development of the new oedometer is described. Results obtained  during  the  preliminary  tests  are  evaluated  through  comparison  with  experimental  data  from  similar tests found in the literature. The current method benefits from continuous control of suction with servo-control of relative humidity using calibrated capacitance hygrometers. The system self-compensates for minor temper-ature changes  and therefore the requirement  for thermal insulation is not as crucial as in vapour equilibrium methods.
