    Significance and Use

    4.1 This test method can be used for quantitative determination of residue and oil distillates in emulsified asphalts for specification acceptance, service evaluation, control, and research. This test method can also be used to obtain residue and oil distillate for further testing. This method may not be appropriate for emulsified asphalts containing latex or polymer; however, some specifying agencies may utilize this method and stipulate a lowered distillation temperature. By stipulating a lowered distillation temperature, the precision and bias statement may not be considered valid. Low-temperature methods such as Test Method D7403 and Practice D7497 are options for obtaining residue for latex or polymer modified emulsified asphalts.

    1. Scope

    1.1 This test method covers the quantitative determination of residue and oil distillate in emulsified asphalts composed principally of a semisolid or liquid asphaltic base, water, and an emulsifying agent.

    1.2 The values stated in SI units are to be regarded as the standard. No other units of measurement are included in this 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, 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.
