1.1 These laboratory test methods cover the frost heave and thaw
weakening susceptibilities of soil that is tested in the laboratory by
comparing the heave rate and thawed bearing ratio with values in an
established classification system. This test was developed to classify
the frost susceptibility of soils used in pavements. It should be used
for soils where frost-susceptibility
1.2 This is an index test for estimating the relative degree of
1.3 The test methods described are for one sample and uses manual temperature control. It is suggested that four samples be tested simultaneously and that the temperature control and data taking be automated using a computer.
1.4 The values stated in SI units are to be regarded as the standard. The inch-pound units 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.
