Full title and description

Standard Test Method for Determination of Emulsified Asphalt Residue By Quick Boil — a short ASTM test method that defines a rapid procedure to determine the mass percent residue of emulsified asphalts by evaporating water and measuring the remaining asphalt residue (quick‑boil evaporation approach).

Abstract

This standard (D8467-22) specifies a quick, quantitative procedure for determining the residue (asphalt content) in emulsified asphalts by heating a known mass of sample to evaporate water and reweighing the remaining material. The method is intended to give results comparable to Test Methods D6934, D6997, and D7404 and is presented for research and informational purposes (not for material acceptance unless precision has been established).

Scope

This test method covers a quick and quantitative determination of residue in emulsified asphalts, producing results comparable to established ASTM methods (D6934, D6997, D7404). It states values in SI units and notes that, because precision statistics have not been developed for this method, it is intended for research and informational use rather than for formal acceptance/rejection decisions. Users are reminded to follow appropriate safety and agency procedures when performing the test.

Key topics and requirements

• Quick‑boil evaporation principle — heat a measured mass of emulsified asphalt to evaporate water, then determine residue by mass percent.
• Apparatus essentials: metal container (≈300 mL), balance accurate to 0.1 g, hot plate (oven optional), tongs, and optional splatter screen.
• Comparability: method designed to yield results comparable to D6934 (residue by evaporation), D6997 (distillation), and D7404 (moisture balance analyzer).
• Units and reporting: SI units are the standard for reported values; notes and footnotes are explanatory and not normative.
• Intended use: research and informational purposes unless precision has been established by interlaboratory studies.
• Safety and competence: results depend on operator competence and equipment calibration; agencies meeting Specification D3666 are referenced as examples of capable testing organizations.

Typical use and users

Used by materials laboratories, research groups, state departments of transportation, paving contractors, and quality control personnel who need a rapid estimate of emulsified asphalt residue for formulation, QC checks, or laboratory investigations. Because the method is short and uses basic equipment, it is convenient for preliminary testing and comparative studies.

Related standards

Directly related and cross‑referenced ASTM methods include D6934 (residue by evaporation), D6997 (distillation of emulsified asphalt), D7404 (residue by moisture balance analyzer), and Specification D3666 (agency testing competency). These standards are commonly used together when characterizing emulsified asphalts.
