Perform unconfined compressive strength test in accordance with AASHTO T 208 or ASTM D2166.

Perform Unconsolidated, Undrained Triaxial compression test on cohesive soils in accordance with Tex118-E, or AASHTO T 296 or ASTM D2850.

Perform Unconfined Compressive Strength Tests and Unconsolidated, Undrained Triaxial Compression Tests on undisturbed 3-inch diameter specimens obtained in accordance with AASHTO T 207 or ASTM D1587.

Specimens shall be free from tailings, cuttings, seams, cracks, and/or other disturbance that may affect the strength result obtained. Do not use specimens with noticeable disturbance for testing. Do not use specimens obtained within the upper 6 inches of the thin-walled tube sampler for testing

Transport specimens for strength test to the laboratory and test as soon as practicable (after sampling) to prevent loss of moisture.
