Standard Method of Test for Consolidated, Undrained Triaxial Compression Test on Cohesive Soils

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.
