1.1 This practice is suitable for recovery of the residue of emulsified asphalts composed principally of a semisolid or liquid asphaltic base, water, and an emulsifying agent. Asphalt base may be pre-modified with polymeric modifiers or latex polymer modifiers may be incorporated into the emulsified asphalt through co-milling or post emulsified asphalt production blending.
1.2 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.
1.3 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.
Significance and Use:
4.1 This practice can be used to obtain residues of emulsified asphalts. The residue may be used for further testing.
4.2 As approximately 5 g of residue is typically obtained, limited testing is possible.
Note 1: Rheological characterization as described in Test Methods D7175 and D7405 are suitable test methods. Additional test methods are being developed suited to the small amounts of residue obtained.
