Geotechnical (OU-105)

Currently adequate for teaching fundamentals, but replacements will be needed in the future to satisfy the needs of increasing numbers of students. The triaxial testing equipment is damaged and needs to be replaced. The triaxial test will be reincorporated into the teaching program as soon as a new unit is acquired.

The equipment is used to teach the 10 experiments of the CEG 4011L - Soil Testing Laboratory I:

1. Water content identification
2. Atterberg limits and indices
3. Mechanical grain size analysis
4. Hydrometer grain size analysis
5. ASTM compaction tests (Stad. and Mod.)
6. In-situ density: sand cone method
7. In-situ density: permeability test
8. Constant head permeability test
9. Direct shear test
10. Stress-deformation and strength characteristics

This laboratory course gives the student a basic understanding of soil properties and behavior, with emphasis on the importance of sampling and testing procedures, as specified by ASTM (American Society for Testing and Materials) for soil and rock testing.
