Test Method Title
Standard Method of Test for Consolidated, Undrained Triaxial Compression Test on Cohesive Soils
AASHTO T 297
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).
Preferred Test Sample Size
Number of Test Specimens
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.
back pressure saturation, cohesive soil, consolidated undrained strength, strain-controlled loading, stress-strain relationships, total and effective stresses, CU, triaxial, pore-pressure
