Standard Test Method for
Expansion Index of Soils1

This standard is issued under the fixed designation D 4829; the number immediately following the designation indicates the year of
original adoption or, in the case of revision, the year of the last revision. A number in parentheses indicates the year of last reapproval. A
superscript epsilon (e) indicates an editorial change since the last revision or reapproval.

1. Scope*

1.1 This test method provides an index to the expansion
potential of compacted soils when inundated with distilled
water.2

1.2 This test method controls variables that influence the
expansive characteristics of soils and still retain a relatively
simple test for practical engineering applications.

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 All observed and calculated values shall conform to the
guidelines for significant digits and rounding established in
Practice D 6026.

1.4.1 The method used to specify how data are collected,
calculated, or recorded in this standard is not directly related to
the accuracy to which the data can be applied in design or other
uses, or both. How one apply the results obtained using this
standard is beyond its scope.

1.5 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.
