【国外标准】 Standard Practice for Effect of Water on Asphalt-Coated Aggregate Using Boiling Water

5.1 This practice is useful as an indicator of the relative susceptibility of asphalt-coated aggregate to water, but should not be used as a measure of field performance because such correlation has not been established. If loss of adhesion due to water is indicated, testing by other procedures should be conducted to further evaluate the mixture.5.2 This practice should not be used for acceptance/rejection by owner agencies.1.1 This practice covers a rapid procedure for visually observing the loss of adhesion in uncompacted asphalt-coated aggregate mixtures due to the action of boiling water.1.2 Units—The values stated in either SI units or inch-pound units are to be regarded separately as standard. The values stated in each system may not be exact equivalents; therefore, each system shall be used independently of the other. Combining values from the two systems may result in nonconformance with the standard.1.3 The text of this standard references notes and footnotes which provide explanatory material. These notes and footnotes (excluding those in tables and figures) shall not be considered as requirements of the standard.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, health, and environmental practices and determine the applicability of regulatory limitations prior to use.1.5 This international standard was developed in accordance with internationally recognized principles on standardization established in the Decision on Principles for the Development of International Standards, Guides and Recommendations issued by the World Trade Organization Technical Barriers to Trade (TBT) Committee.
