Standard Test Methods for One-Dimensional Swell or Settlement Potential of Cohesive Soils
|Publication Date:||10 May 1996|
|ICS Code (Earthworks. Excavations. Foundation construction. Underground works):||93.020|
1.1 These test methods cover three alternative laboratory methods for determining the magnitude of swell or settlement of relatively undisturbed or compacted cohesive soil.
Note 1-Refer to Section 5 to determine the best method for a particular application.
1.2 The test methods can be used to determine (a) the magnitude of swell or settlement under known vertical (axial) pressure, or (b) the magnitude of vertical pressure needed to maintain no volume change of laterally constrained, axially loaded specimens.
1.3 The values stated in SI units are to be regarded as the standard. The values stated in inch-pound units are approximate.
1.4 This standard does not purport to address all of the safety concerns, if any, associated with its use. It is the responsibility of the user of this standard to establish appropriate safety and health practices and determine the applicability of regulatory limitations prior to use.
