(Practice)Standard Practice for Recovering Residue from Emulsified Asphalt Using Low-Temperature Evaporative Technique
Standard Practice for Recovering Residue from Emulsified Asphalt Using Low-Temperature Evaporative Technique
SIGNIFICANCE AND USE
3.1 The procedure described in this practice is used to obtain a residue from an emulsified asphalt that may be used for further testing in devices such as a dynamic shear rheometer. The lower evaporative temperatures of this procedure provide conditions that are very close to those of application techniques for these materials. This practice could be used in place of recovery techniques such as those of Test Methods D6934 and D6997, when the temperatures used in those standards would negatively affect the residue.
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 Specification D3666 are generally considered capable of competent and objective testing, sampling, inspection, etc. Users of this standard are cautioned that compliance with Specification D3666 alone does not completely ensure reliable results. Reliable results depend on many factors; following the suggestions of Specification D3666 or some similar acceptable guideline provides a means of evaluating and controlling some of those factors.
SCOPE
1.1 This practice covers a method for recovering the residue from emulsified asphalts such as those specified in Specifications D977 and D2397/D2397M using a low-temperature evaporative technique that is similar to pavement conditions. The recovered residue can be used for further testing as required.
1.2 The values stated in SI units are to be regarded as the standard. The values given in parentheses are for information only.
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.
