AASHTO T 296-10 (2020) is a standard method that provides guidelines for testing the unconsolidated, undrained compressive strength of cohesive soils using a triaxial compression test. The purpose of this test is to determine the strength and stress-strain relationships of cylindrical soil specimens under undrained conditions. The test involves subjecting the soil specimen to compression at a constant rate of axial deformation, with the deformation being controlled by the strain.

This method is applicable to both undisturbed and remolded cohesive soils. The test is performed on cylindrical specimens, and the results obtained provide valuable information about the soil's shear strength and deformation characteristics. By measuring the axial stress and axial strain during the test, the unconsolidated compressive strength of the soil can be determined.

The standard provides detailed instructions on specimen preparation, test apparatus, and procedures to ensure accurate and reliable results. It also covers the measurement and calculation of stress-strain relationships and provides guidelines for reporting the test results. Following this standard ensures uniformity and consistency in conducting the triaxial compression test for cohesive soils, allowing for reliable comparisons and analysis of soil samples.
