Standard Method of Test for
Direct Shear Test of Soils under Consolidated
Drained Conditions
AASHTO Designation: T 236-081
ASTM Designation: D 3080-72 (2003)
SCOPE
1.1.This method describes procedures for determining the consolidated drained shear strength of a soil material in direct shear.
The test may be conducted in either a single shear or in a double shear, as shown in Figure 1.
The direct shear test is well-suited to a consolidated drained test because the drainage paths through the test specimen are short, thereby allowing excess pore pressures to be dissipated fairly rapidly.
The test can be made on all soil material, 2 and on undisturbed or remolded samples.
