Behaviour of locked sand during cavity expansion
… to the conventional understanding of the stress-dilatancy and drainage properties of sands. These deposits have a dense locked sand structure with high viscosity bitumen occupying a large portion of their void space. Steam Assisted Gravity Drainage is a method widely used for extraction of …

Experimental and Numerical Study of Rubber Intermixed Ballast System Subjected to Monotonic and Cyclic Loading
… has been developed to explain fundamentally the stress-dilatancy behaviour of RIBS. In a practical perspective, the application of RIBS in real-life tracks is elucidated to encourage railway asset owners and R&D stakeholders to adopt and implement RIBS given its proven sound geotechnical and …

Effects of maximum particle size and sample scaling on the mechanical behavior of mine waste rock; a critical state approach
… and tested at the same levels of mean effective stress (p') in a large-scale triaxial device. Intrinsic critical state parameters were defined for each material in conventional scale triaxial testing. Results suggest the parallel gradation technique provides a reasonable way to estimate values of …

Creep behaviour of shallow foundations on sand and its implication to soil–structure interaction
… of imposing a creep period. The analysis of the stress–dilatancy behaviour reveals that the development of interlocking between sand particles during creep is the cause of these aging effects. At the foundation scale, an elasto-viscoplastic macro-element model that can simulate the time-dependent …

Biocementation of Road Foundations: Element Testing, Physical Modelling, and Micro-Scale Characterisation
… biocemented aggregates. The observed changes in stress-strain responses, strength and stiffness evolution, and stress dilatancy are consistent with those reported for biocemented and conventionally cemented soils. The relatively low cementation levels used effectively rectified the deficient …
