    Significance and Use

    3.1 This test method can be used for quantitative determination of residue in emulsified asphalts at a temperature of 135 °C (275 °F) with a 60-min distillation test using current distillation apparatus. This method is suitable to obtain residues for service evaluation, quality control, and research. This distillation method is not intended to produce residues equivalent to the Test Method D6997 260 °C (500 °F) distillation procedure.

    1. Scope

    1.1 This method covers the quantitative determination of residue in emulsified asphalts composed principally of a semisolid or liquid asphaltic base, water, and an emulsifying agent. The emulsified asphalts will generally contain polymeric materials. It is especially suitable for emulsified asphalt residue properties that may be altered at the high-temperature 260 °C (500 °F) distillation. Since there is currently not a precision statement for this procedure, it is recommended to the user that this procedure not be used for buy/sell purposes at the present time.

    1.2 The values stated in SI units are to be regarded as the standard. Values in parentheses in inch-pound units are provided for informational purposes only.

    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, health, and environmental practices and determine the applicability of regulatory limitations prior to use.

    1.4 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.
