Test Method Title
Standard Method of Test for Consolidated, Undrained Triaxial Compression Test on Cohesive Soils
Reference Number
AASHTO T 297
Material
Soil
Test Property
Strength, Stress-strain relationship
Description of Test
This test method covers the determination of strength and stress-strain relationships of a cylindrical specimen of either an undisturbed or remolded saturated cohesive soil. Specimens are isotropically consolidated and sheared in compression without drainage at a constant rate of axial deformation (strain controlled).
Number of Test Specimens
3
Test Specimen Size
Minimum of 1.3 in diameter, with a height-to-average diameter of 2-2.5, with minimum particle size 1/6 the diameter.
