Standard Test Methods for
One-Dimensional Expansion, Shrinkage, and Uplift Pressure
of Soil-Lime Mixtures1

This standard is issued under the fixed designation D 3877; the number immediately following the designation indicates the year of
original adoption or, in the case of revision, the year of 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 These test methods provide procedures for conducting
expansion, shrinkage, and uplift pressure tests on compacted
soil-lime mixtures and can be used to determine the lime
content required to achieve desired control of volume changes
caused by increases or decreases of moisture.

1.2 The tests can be used to determine (1) the magnitude of
volume changes under varying load conditions, (2) the rate of
volume change, and (3) the magnitude of pressure change as
moisture changes of the soil-lime mixture take place. The
permeability of soil-lime mixture can also if desired, be
determined at the various load conditions.
NOTE 1—Changes in field conditions can have major effects on the
expansion and shrinkage characteristics of expansive soils. Therefore, to
the greatest extent possible, initial and anticipated future field conditions
should be duplicated, particularly with respect to moisture and density.

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

1.3.1 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.

1.4 The values stated in SI units are to be regarded as the
standard. The values given in parentheses are for information
only.

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.
