AASHTO T226
Full Name
AASHTO T226 – Standard Method of Test for Triaxial Compressive Strength of Undrained Rock Core Specimens without Pore Pressure Measurements
Scope
This test method covers the determination of the strength of cylindrical rock specimens in an undrained state under triaxial compression loading.
The test provides data useful in determining the strength and elastic properties of rock, namely: shear strengths at various lateral pressures, angle of internal friction (angle of shearing resistance), cohesion intercept, and Young’s modulus.
