Formerly under the jurisdiction of Committee D04 on Road and Paving Materials, this test method was withdrawn in August 2019. This standard is being withdrawn without replacement due to its limited use by industry.
Значение и использованиеThis test method is useful as an indicator of the susceptibility to moisture of compacted bitumen-aggregate mixtures.
Note 1—The quality of the results produced by this standard are dependent on the competence of the personnel performing the procedure and the capability, calibration, and maintenance of the equipment used. Agencies that meet the criteria of Standard Practice are generally considered capable of competent and objective testing/sampling/inspection/etc. Users of this standard are cautioned that compliance with alone does not completely assure reliable results. Reliable results depend on many factors; following the suggestions of or some similar acceptable guideline provides a means of evaluating and controlling some of those factors.
Область применения1.1 This test method covers measurement of the loss of compressive strength resulting from the action of water on compacted bituminous mixtures containing asphalt cement. A numerical index of reduced compressive strength is obtained by comparing the compressive strength of freshly molded and cured specimens with the compressive strength of duplicate specimens that have been immersed in water under prescribed conditions.
1.2 Units—The values stated in inch-pound units are to be regarded as standard. The values given in parentheses are mathematical conversions to SI units that are provided for information only and are not considered standard.
1.3 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.
