15. Supplementary Notes Project performed in cooperation with the Texas Department of Transportation and the Federal Highway Administration; Project Title: Implementation of Research Results Regarding Shear Strength and Stability of Embankments 16. Abstract A number of TxDOT-sponsored studies and research projects have been conducted over the years regarding shear strength and slope stability i...

This research work presents a case study of rock mass characterization on diversion tunnels at Diamer Basha Dam, Pakistan. Geological and geotechnical studies were performed to characterize the rock mass along the axis of diversion tunnel. The core specimens retrieved were tested in laboratory and physical and mechanical properties of the rock mass were determined. Detailed discontinuity survey...

The mineral calcium sulphate transforms from anhydrite through bassanite to gypsum and then can convert back to bassanite and anhydrite. This transformation of calcium sulphate causes volume change that adds to the potential hazards with indigenous soils containing expansive clay minerals. Heave and settlement are the most important geotechnical problems associated with many argillaceous soils ...

A desktop Geographic Information Systems (GIS) for Geotechnical Information Management system has recently been developed to assist geo-technical managers, planners through flexible application with all common desktop GIS functionalities and customized tools like Borehole Viewer and Stripchart to relate alignments and cross-sections to a specific location and/or region on the map, and create th...

The aim of this paper is to discuss issues based on foundation design in conjunction with partial factor format for the future development of foundation design codes. That the resistance factor approach is superior to the material factor approach in practical terms for foundation design is concluded. Then, a common procedure from geotechnical investigation/ testing to determine the design geote...

Cone penetration testing (CPT) is one of the most efficient and versatile methods currently available for geotechnical, lithostratigraphic and hydrogeological site characterization. Currently available methods for soil behaviour type classification (SBT) of CPT data however have severe limitations, often restricting their application to a local scale. For parameterization of regional groundwate...

The utilisation of industrial bi-products such as cement kiln dust (CKD) is of increasing importance as an option for stabilising contaminated sites due to its pozzolanic nature and also in view of minimising the environmental impact. The experimental programme was carried out in the present study to evaluate the efficacy of CKD as stabilising agent at different percentages 2%, 6%, and 14% (w/w...

This technical note describes a set of direct simple shear (DSS) tests that characterise the evolving geotechnical properties soft soil, through loading history represents episodic load...
