  • The mechanical properties of a high plasticity expansive clay 
    Gaspar, Tiago Alexandre Valentim; Jacobsz, Schalk Willem; Heymann, Gerhard; Toll, D.G.; Gens, A.; Osman, A.S. (Elsevier, 2022-06)
    The mechanical properties of a high plasticity expansive clay from South Africa are reported. The experimental programme considered wetting after loading tests followed by one-dimensional consolidation and unloading of ...
  • Polyethylene glycol and membrane processes applied to suction control in geotechnical osmotic testing 
    Vandoorne, Rick; Grabe, Petrus Johannes; Heymann, Gerhard (Taylor and Francis, 2022)
    The osmotic technique in geotechnical testing of unsaturated soils is a promising technique to control soil-water potential. This technique is an alternative to the axis-translation technique. In this technique an aqueous ...
  • Soil suction and temperature measurements in a heavy haul railway formation 
    Vandoorne, Rick; Grabe, Petrus Johannes; Heymann, Gerhard (Elsevier, 2021-11)
    Transportation foundations around the world exist predominantly in an unsaturated state. Support for the adoption of unsaturated soil mechanics in routine geotechnical engineering is ever-increasing. However, the measurement ...
