ASTM D7944-15

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.

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