The Texas Department of Transportation (TxDOT) uses the Texas modified triaxial design procedure as a design check to the Flexible Pavement System (FPS) design method. This report describes a computer program researchers developed to check the adequacy of the thickness design from FPS based on the Mohr-Coulomb yield criterion.

Forty-eight soil samples taken from twelve different locations in Kuwait City and the Jahra area were used in four series of drained and undrained triaxial compression tests using multistage and conventional test techniques on undisturbed and remolded specimens. Automatic system for uniaxial and triaxial tests on rock cores, including STRESS PATH and PERMEABILITY determination Layout of the automatic system for uniaxial and triaxial tests (with stress-path analysis) and permeability determination Hoek cell fitted with permeability end cups for permeability test Screenshot of a stress-path triaxial test on rock performed with the ADVANCED system (load

In this paper, newly developed 3D AE tomography will be briefly introduced followed by the application of triaxial rock shear test. Through the application the applicability of 3D AE tomography [3] for diagnosis of actual deterioration/ damages of infrastructures will be discussed. The first stage of any construction strategy is to determine whether the soil on your site can accommodate your project. Our triaxial test identifies the properties of the soil on your site and determines its ability to support your structure.

Unconsolidated Undrained Triaxial Test (UU Triaxial Test) As drainage is not permitted and consolidation is not necessary, this test is very quick, and also referred as Q-test. As drainage is not permitted, u increases right after the application of σ 3’ as well as after the application of … Feb 14, 2006 · Is the answer to this question at least partially application specific (irrespective of legal design requirements)? Here is an excerpt from Holtz and Kovacs (section 10.5) that addresses this issue: The advantages of the triaxial test over the direct shear …
