Triaxial relaxation testing of a frozen sand
Canadian Geotechnical Journal, 1995The objective of this investigation was to evaluate the potential use of the laboratory stress relaxation test to determine the creep and strength properties of frozen soils. This paper presents the results of a series of laboratory step-loaded relaxation tests performed on frozen Ottawa sand under triaxial compression conditions and compares three ...

Triaxial tests on an unbonded locked sand
Géotechnique, 2004This paper describes the results of a series of triaxial tests carried out to investigate the influence of fabric structure on the yield and failure behaviour of intact Reigate silver sand—a locked sand characterised by minimal cement content, large grain contacts, and a relative density index of 136%.

Triaxial Testing of Bituminous Mixtures
1959For approximately twenty-five years the attention of paving design engineers has been directed in part towards the use of a triaxial shear strength method of test to evaluate the properties of bituminous mixtures. Interest in this form of test, particularly as a means of evaluating fundamental strength properties of bituminous mixtures, has become ...

Triaxial Testing of Unsaturated Soils
2013This paper highlights the key features of triaxial testing of unsaturated soils. The modifications to a conventional triaxial apparatus and the test procedures for various unsaturated soil triaxial tests are described. Test results for an undisturbed residual soil tested under consolidated undrained (CU) and constant water content (CW) conditions at ...

An Automated Triaxial Testing System
1988This paper describes a recently developed automated triaxial testing system. Loading is controlled by a closed-loop feedback scheme capable of performing stress- or strain-controlled tests in the standard triaxial environment. The system has two control channels allowing separate control of both the axial load and the chamber pressure ...

Triaxial Relaxation Tests on a Soft Clay
1988Results of consolidated undrained triaxial relaxation tests on a soft sensitive clay of eastern Canada are presented and discussed. The initial consolidation phases of the traxial tests are carried out under both isotropic and anisotropic stress conditions.

Triaxial testing beyond yielding
2017This paper is continuation of work published at ISOPE 2015, where capabilities of undrained triaxial testing were presented. Now, drained loading is emphasized, recovery of disturbed sand properties is observed.After liquefying or yielding, sand becomes disturbed: stiffness and resistance to liquefaction become compromised.

A brief review of the history of the development of the triaxial test for road work, up to current practice, is given, together with a discussion of the stress forms in road pavements and the applicability of triaxial methods thereto. The nature of the Mohr diagram as an interpretation is given, with mention of other methods of use and interpretation ...

Computer controlled triaxial testing system
1996This paper describes enhancement of a computer controlled triaxial testing system to perform triaxial tests. The commercial system uses a microcomputer to operate three digital pressure volume controllers that control and measure pressure and volume change of fully saturated soil specimens.
